Klara’s apartment was our favorite place to stay of all the cities we visited in Europe. The apartment was immaculately clean and actually quite large. The heated floors in the bathroom were a nice touch on chilly nights and the big windows provided a lot of great natural light in the mornings. The building is an older, renovated building and sometimes was a little dark when entering at night, but otherwise everything was great - the neighborhood is quiet and felt completely safe. I would also caution that because the building is older, sounds might travel more easily. The unit next to us (which I also think is an AirBnb) complained to Klara multiple times that we were loud but all we were doing was talking in our own space or watching a movie. It may have been a fluke with this particular individual, but I’d be cautious anyway.
