Heating control was limited to 20 degrees. We had to use the small electric heaters, which are not great and 2 of us ended up sick by the end of the trip. Also, I asked beforehand if it would be ok to leave our bags in the flat a bit earlier at around 2 instead of the check-in time 3, and was directed to a locker service with a 10% discount. While I understand the official checkin time is 3, in the spirit of being a helpful nice host instead of a corporation managing airbnb services, I think it would be ok to offer early bag drop instead of directing to a paid service to get a commission. Finally, the building's entrance door was open (probably due to some construction going on), with a lot of dirt and debris inside, which does not make a great first impression and is not very healthy either. Otherwise, really great location and good size flat.
