I already left the front desk know, there is a terrible noise from the fresh air supply to the room. The room doesnt have an opperable window, so, the builder decide to run a central fresh air supply. The opening for that is way too small and make a terrible air flow noise 24/7. I m very sensible for noise during night, so I tried to close this opening with a T shirt, partly helped. Other than this, the Hotel is a nice place, with a central location. I might have to go to a different place next time.
