Longevity hotel in Karlovy Vary: the Prezident case

Karlovy Vary is a spa town with 650 years of healing history and the cradle of Europe's longevity movement. At the Luxury Spa & Medical Wellness Hotel Prezident, spa medicine first met Longevity Resort.

The platform

Longevity Resort: the longevity platform for hotelsLongevity Resort is a white-label platform: it reads Garmin watch data, builds a course from the hotel's own treatments and offers the guest paid ones. The doctor signs.How the platform prescribes procedures: algorithm and night loopAn algorithm builds the stay from the hotel's procedures, the intake form, the rooms' hours and how long each takes; the night corrects it, the doctor moves paid work.How Longev AI learns: rules, data and a tested forecastLongev AI runs on explainable clinical rules over the guest's own baseline, collects exposure-to-response pairs on top and openly measures its own forecast error.Wellness & Lifestyle Intelligence and GDPR: the legal frameThe portal supports a way of living; it does not diagnose and does not prescribe. Health data is processed under GDPR — on the guest's explicit consent, on an EU server.Pricing: Setup, Base and Active Guest — what the price includesThree parts: Setup — €2,500 for the launch, Base — €800 a month (800 guest accounts on smartphones and 10 active guests with devices), Active Guest — €8 per stay from the 11th active guest. No hidden fees.Garmin Daily Suggested Workouts: How the Algorithm WorksThe Garmin/Firstbeat Daily Suggested Workouts (DSW) algorithm recalculates your recommended training load every day based on heart rate variability, sleep, and training stress. Longevity Resort programmes are built around it.Multilingual portal: 36 languages for guest and doctorThe portal speaks every guest's language: interface, calendar and recommendations in 36 languages, Arabic and Hebrew included. The doctor writes in their own language, the guest reads in theirs.

Longevity programmes

Six markers from the watch show how it goes.Joints & Mobility: what the programme containsA balneology course for joints and spine: 14 days by default, 5 minimum. Peat packs, sulphur baths, underwater massage, aqua gym; six watch measures show how it goes.Immune Reboot: programme 10, hardening by the numbersProgramme 10 of the longevity resort: contrast heat, salt steam and oxygen train the barrier immunity, while six numbers from the night keep the dose in check.Aesthetic Longevity: the anti-age and lymphatic drainage courseA 7-day course (3 minimum): lymphatic drainage, carboxytherapy and professional skincare on a spa base.

It lifts nervous exhaustion and unloads the musculoskeletal system.

The longevity route

The longevity route: how it worksA walk along a marked Karlovy Vary trail wearing the hotel's watch. It takes a couple of hours, needs no sign-up, and ends with your measurements in your inbox.The walk screen: what every number meansThree numbers, a pulse corridor, a voice and a map that leads. A reading of the screen you hold on the trail.The portal cannot see where you are: why, and how to turn it onThe walk is running, the clock is ticking, and the kilometres stay at zero. Every reason a phone withholds your location, and what to press for each one.The walk is over: what happens nextOne press of «Finish» and the walk is saved, the route is marked as walked, and you are already looking at its card. What is on that card, where the link goes, and what to do when the pulse has not arrived yet.The walk's folders: numbers, postcard and verdictThe page of a single walk: «Results» with the numbers and the postcard, «Recommendations» with the questionnaire's verdict — and an honest note for anyone who walked with a phone alone.

Managing the portal

The desk: working with the appsWhat reception does when a guest arrives and leaves: issuing a kit, checking the link, taking it back and erasing it — screen by screen, no commands.The numbers a doctor changes procedures byThe morning sheet compares the guest's night with their own average and proposes a correction. Here are all the thresholds, all the flags and what follows from each.The panel: who is in the hotel and what each role seesThe staff's first page — a line for every guest wearing a kit right now. Plus the panel's sections, the roles and «the guest's account».The morning round and the doctor's messagesAn A4 sheet per guest, Garmin's own verdict printed beside ours, and one object for both «a recommendation to a patient» and «an announcement to the house».The desk: the longevity routeIssuing a kit for two hours, the visitor's three letters, the «Walk recorded» line and the «SEND» button. Everything the person at the desk does, in order.

The guest's account

Signing in: four doors and no password on paperHow a guest reaches their account — by a link from a letter, by e-mail and password, through Google, or from the desk's QR code. And why a session lasts two years.The account: what is whereTen sections, two ways to reach them and one page of services. A reading of the table of contents a guest walks for a fortnight.LONGEVITY: the front page and «Today's report»The day's rings, the measurement cards and the column of advice on the right. A reading of the screen a guest lands on — and the rule that puts a date under every number.Health: the eleven roomsSleep, steps, floors, weight, oxygen, breathing, fitness age, stress, Body Battery, calories and HRV — a room per measurement. What is in each and where its numbers come from.The stay calendar: day, week, month and what is on in townOne list of events with five readers: the calendar, the watch face, the walk app, the phone reminders and the doctor's sheet. Plus what the town itself is doing.Procedures: booked and requestedWhat is already in the schedule, how to ask for more, and why a request has no «approve» button. The second and third tabs of «Drinking cure & procedures».The drinking cure: a doctor's card turned into a screenServings by the clock, a spring number on each, the «drunk» mark and a small map to the vase. How the spa water works inside the portal.Nutrition and water: the programme's table and the day's balanceWhat is on the table under your programme, and how much you have drunk today — from four sources at once. The two rooms of «Nutrition».Longevity programmes: configurator, price and correctionsAn eleven-question quiz assembles a day-by-day programme out of the hotel's 139 treatments, prices it, and then keeps correcting the plan by what the watch has seen.Your personal data: two consents, an export and a deletionWhat the portal keeps about you, who else sees it, how to take it all away in one file and how to delete it. With buttons in the account, not a letter to the hotel.Your own device: a guest's watch instead of the kitWhat the portal can do with another maker's watch, a ring, or nothing but a smartphone — and what it honestly does not promise in that case.

Equipment

Setting up the kit: the phone and the watchThe phone guides the walk by voice with no network at all; the watch writes the night. What to switch on on the phone and what must be switched off on the watch — step by step, with screens.Hotel Wi-Fi for Garmin watches: what to prepareGarmin watches and scales need a 2.4 GHz network of their own, WPA2 password, no sign-in page. The second path skips it: the kit's phone in the room.The hotel's watch: getting startedWhat is installed on a loaner watch, in what order it is switched on, and why installing is not the same as being visible.The watch face: what every figure meansThe screen from top to bottom: the pulse and its arrow, the day's events, the blinking corridor line — and every state a guest can meet.The Walk app: screens and buttonsThe glance, the day's pages, the walk with its route line, the functional tests and the code entry — every screen explained, and what to do when something is off.What the watch sends to the portalThe full list: which parameters are collected, by which route, how often, what each number then looks like in the guest's account, and what the doctor reads from them.The functional tests, step by stepThree tests are taken by the watch itself. Every screen and every button in order — enough to show a guest without explaining.The pulse corridor: where those numbers come from«Target 128–145 bpm» on the walk screen is not a hospital average but your own range, worked out from your age and your answers.What the watch measures: every metric in orderResting pulse, variability, Body Battery, stress, steps, floors, calories, oxygen, breathing and sleep — what each number means and what moves it.
