A very nice flat in a great location. It is high up (nice, because there isn't much city noise) and has a small elevator so you don't need to walk many stairs.
Downsides: The oven was broken which we didn't know about when we booked in the beginning of the year and there were quite many ants on the lowest level (second bedroom, hallway and bathroom) - they didn't bother us much but still they can be a little annoying. Also the wifi didn't work most of the time which wasn't so nice.
Still the hosts were always good in communication and helped us out when needed.
