As the other reviewers have written, this is a dream apartment. I was blown away by how amazing this place was, and Francesco was a fantastic host. We were a group of four (two couples), and we had more than enough room. This apartment definitely works for a larger family and would also be fine for three couples.
* Apartment - beautiful, spacious, and very clean. Everything is brand new, the beds are comfortable, the air conditioning works really well (separate air conditioner in each room), and there is a washer for clothes. The double paned windows keep the apartment really quiet. We loved the balcony, and the view of the Duomo was incredible.
* Location - couldn't be better. Right next to the Duomo on a quiet pedestrian-only side street. You can still get here by taxi, as cars can go on the intersecting street at the corner.
* Host - Francesco was responsive and very helpful. I had a few questions during our visit (where to find a bookstore, how to reserve a taxi for an early morning departure), and he was always quick to respond.
Francesco, thank you for making my visit so special! I definitely hope to stay here again on my next visit to Florence.
