This apartment is wonderful! It is in a fantastic location with the major destinations all within walking distance. The terrace is one of the highlights, with the 2 outdoor cats that like visitors. You should note that there are 84 stairs to get to the apartment... it's a big hike that was fine for us but others should be aware of the physical requirements to access the apartment.
The apartment itself is a linear series of four rooms, and you must walk through one room to access the next. There may not be as much privacy as some families are used to. All four rooms have sliding doors to the terrace. The first room is the entrance, and has a small table. There is a half flight of stairs to the kitchen and a bathroom. The second room has a couch, a half flight to a bathroom, and another half flight up to a bed. The third room has a nice comfortable bed. The fourth room has a desk and a bathroom, and stairs up to a bed. It also has access to a large rooftop patio, that is largely unused but is accessible. All rooms are nicely decorated with artwork and antiques, as the photos here on Airbnb show.
We had a great stay here! We came in December, and while every day was above 50F, it wasn't warm enough to fully enjoy the terrace, which has a second kitchen and a larger table. I would easily stay here again!
