The flat is very clean, cozy and located close to the city center. All main attractions, many cafés and restaurants can be reached on foot easily.
Catarina was very friendly and helpful. Also extremely felxible for Check-In.
My flight was delayed, so I was way too late for our original check-in time, but it all worked out perfectly in the end.
The only con are the 2 small windows, which make it hard to lower the humidity in the flat. This could get quite uncomfortable during rainy days or for people who are sensitive in regards to that.
All in all I can recommend the flat as home-base for discovering the city on a short trip.
