Guest app and pre-check-in for hotels, apartments and flex living

Sense is a guest app for operators of hotels, apartments and flex living spaces. The guest does the pre-check-in from their phone, receives a digital key, books services and pays from the app. The operator manages the whole stay from a dashboard connected to their PMS, their locks, the official traveller registry and payments. We built the complete product for Sense Living Spaces and run it in production in its first property in Luxembourg.

A modern property lives spread across systems that do not talk to each other. Bookings sit in the PMS, locks have their own software, traveller registration goes through the official portal and payments elsewhere. Every gap is covered by a person at reception, by hand, every day. Sense wanted a product that worked for hotels, holiday apartments and flex living alike. The guest had to arrive at a reception that already knew everything. The operator had to charge outstanding balances against the PMS folio, sell its own and third-party services, manage parking by space and night, all with the reliability a business open all year demands.
