Very rude!!!! Never had a host who was that rude with his guests. Suspicious all the time, said we did this, we did that.. He saw it on camera. Actually there is not even a camera, just wanted to find a guilty one. The bedding extremely dirty under the covers.
The appartement is on the last flor, the key box is there as well. You can use the elevator with the key only, so don't make the mistake to go up with your luggage. Better go get the key and then bring the luggage up by elevator.
The overall appartement is nice. You can stay there if you won't need to contact the host, otherwise better save your nerves.
