With a lot of luck I manged finally to enter my hotel room. The check-in process using an app was not described upfront and was quite exhaustive as you even need to tell, how you arrive (car/train/plane) including flight number before you get told your room number. Reception is not available and phonecalls lead in 80% of the cases to nothing. The app is unstable and broke down after my second entering to the room so I could not leave the room once again.
