The room that we were put in was in very bad shape: the walls were covered in mold, and there was an ugly smell emanating from the bathroom. A room in such a condition should not be rented out.
After we complained, we received the offer of relocating to another room, which was indeed in much better shape (although the first signs of deterioration are already visible there as well). We were happy with this second room.
I am still giving a bad review, however, because the first room should never have been listed to begin with. The pictures are misleading, it is in very bad shape. That we were relocated to a better room, does not change this. Indeed, it raises the suspicion that the owner is very much aware of the bad condition, but still rents out the room in the hope that the guests will not complain. If they do complain, the owner tries to appease them, as they did with us. (I wonder what they do if there is no better room available). I do not find this a decent practice, which is why I am giving a bad review.
