We really enjoyed our stay at the apartment. The location was pretty much perfect - quiet area but very close to everything - restaurants, nightlife, historical sites - we walked almost everywhere.
The apartment itself is nice, cozy and clean. It even has a dressing room. Though we would have appreciated a bit more kitchen basic "equipment" like salt, cooking oil or tea. The balcony is amazing for a morning coffee or late night glass of wine.
The only issue we had is that the upstairs neighbours were quite loud - it is probably because the building is old, but you can hear almost everything from them. A few times we were woken up by them stomping around the apartment or talking very loudly at 2 or 3 AM. So I recommend you bring ear plugs if you're a light sleeper like we are.
