The apartment is really spacious and well equipped. but not clean as expected. We had no water in the kitchen whole stay. There is a woman (host's mother or some relative) who sits and smokes in front of the apartment all day. It is not a big deal but it is kind of annoying. On the other side, they left us to keep luggage until 14 on our check out, which was a nice gesture.
The location of this apartment is fabulous. The building is next to the Serbian embassy, literally 50 meters from Charles bridge.
