The apartment had a few issues: the internet wasn't working properly (when it did it was very slow). Throughout our stay we saw a mouse (not a pet) running around the apartment, and made us feel a bit uncomfortable. The offered solution was mouse traps, which we didn't agree to. Also, the bathroom had a weird smell. Finally, one of the bedrooms had an old door behind the closet, and you could easily hear the people on the apartment next door.
Positive things: close to undergroud and spacious rooms.
