However, I did have some problems in the end with the owner. I stayed there with my cat and when I left there was probably some of the hairs left on furniture. The rest of the apartment was clean. So, in total the apartment was at least as clean as when I moved in, since there were hairs of the prior person in the bed, cut-off toenails in the bathroom etc. But here is where the problem started with the owner. He didn’t come when I left and then suddenly later, he sent me a message demanding ~60€ as a cleaning fee. I resisted, because on one side the apartment was not perfectly clean when I moved in either and on the other side the demanded fee was way too high. The owner insisted on this amount and started to threaten me if I don’t pay it immediately. I compared the price to the prices of professional cleaning services. I could only look at the one with information in English and I guess they were already above average, but they charged around half of that price for a whole apartment and this was only about using some sticky hair remover for the furniture. When I confronted the owner with the results from my search, he suddenly changed his mind and we made an agreement and I paid some amount just to settle this case. However, I wonder whether he is trying to get 60€ from every person that stays there and then only does the minimum cleaning and this issue could have been handled much better than in his aggressive way.
Only downsides are that most closet space is already filled so you're left with only one with dificult sized drawers with a chair in front of it. And there's no vacuumcleaner, so there are always some crumbs and dust on the floor. Overall I really enjoyed my stay.
