The apartment is clean and cosy. Our stay was in the winter, so we didn't really had a chance to take advantage of the wonderful roof terrace. But I'm sure it is a huge bonus in warmer months.
The location of the apartment is excellent- not far from the center city, but at the same time, the neighborhood is quite peaceful.
The only reason I'm not giving five stars are the problems with the wi-fi. The communication with the hosts is perfect, and they did their best to help, but during our stay it took us a little bit of a nerve. But don't worry! We were one of the first guests in the apartment, so I'm sure by the time you get there, the problem will be completely solved.
And one more thing - older people who are not in good shape should be warned that the staircase to the apartment (4th floor) is quite a climb:)
