We just returned from 10 nights at Francesco's apartment. Wow, what an amazing place. Modern, clean and spacious. The view of the Duomo must be the best in Florence. One block from the Duomo and walkable to everything. AC and an elevator make this apartment perfect, not to mention plenty of space with 3 bedrooms and 2 bathrooms.
Francesco was amazing to work with. Very easy booking and communication both prior to our arrival and throughout our stay. He was so welcoming on our arrival and willing to assist us in any way. We would stay here again in a heartbeat. If you're even thinking about booking this place, just do it. Morning coffee on a terrace right in front of the Duomo is something you won't forget.
