We stayed in Silvia's place during the Catholic Easter. Very clean and convenient. Silvia is also very kind and communicative. The apartment offers all the amenities one would need for staying there a few days. The apartment is located in the heart of the historic center of Florence. All the great attractions, monuments and museums are a short walk away. Many shops and restaurants close by as well.
The only thing to be aware is that the room is on the forth or fifth floor. It is about 110 stairs up, so if you are old or not fit enough, and especially after a long day walking around and climbing the stairs of Palaccio Vecchio or the Duomo, then it can be a bit tough.
