For everybody who has no proble ms with walking quite a few meters up, the place is located in a great area, also with many bars and restaurants nearby. Still, it tend to get very exhausting quickly and shall rather be recommended to fit und young people. Also, the neighborhood is pretty loud with loud music (not at night, though!), dogs barking almost the whole day and a few additional minor things. All not necessarily a problem, but it should simply be mentioned.
I really appreciated the flexibility of the owners, also in terms of having the chance for a late checkout.
However, there are a few things which I am sure can be improved: The interior is very old and tends to become more and more shabby. There is a very strong bad smell in the kitchen area, maybe it's coming from some of the tubes. The bath is ways smaller than it looks on the pictures and it is almost impossible to not water the whole room/get touched by the old plastic paper while showering. And first of all, considering all this and comparing the price with other AirBnB flats and even hotel rooms, the owners honestly charge too much. I transferred to another place after a few days (as it was planned) which was very clean, new and more spacious for around 60 percent of the price.
