A difficult review to write as there were many things we enjoyed and others that were very difficult. We stayed for 6 weeks.
It's a beautiful, comfortable, apartment with 2 of the best bathrooms we've ever had in our many trips to Italy. It's as nice as it looks in the photos, and is in a very good location.
It has excellent internet.
Things to know:
It has 19 steps up to the apartment.
Cristina is an excellent host and was readily available.
We have stayed in the city centers of Naples, Palermo, and Rome (several times) but have never before had to deal with the noise as we experienced here. The listing states " in a quiet street" but beginning every morning at 5:45am several storage garage doors directly below the apartment are opened and for the next few hours vendor carts are taken out, moved around, and rattled down the cobblestone alley. In the afternoon and evening it is repeated in reverse.
While we were able to get partially used to and accept much of that, the other issue that was difficult was the lack of natural light. The small windows never got any direct daylight. For a few days that could be ok. The listing says it has "a city skyline view" but actually only looks out at a wall across the narrow alley.
Note, we are retirees and spend the majority of our days in apartments so these things might not bother most people. Then it could be a very good choice for a stay in Florence.
