I'll start with the good things, the location of the flat was good, and the hosts were really nice and were trying to help us before and during our stay. However, the flat was not designed for proper living standards. It has no windows, which caused a lot of mold everywhere, and the place was very stinky. The flat had a lime stone walls, that were kept on crumbling and the floor was dirty all the time. Due to the lack of ventilation the walls were moist all the time that contributed to the bad smell there. We were staying during April, which was a little bit cold during the night, but there were no option for heating in the bedrooms. The second bathroom is in a cellar, and it was very unpleasant to go there, plus the ventilation (window) of that bathroom was directly to the dining area (you could practically see someone sitting on the toilet from the main floor).
