This very comfortable apartment was perfect for our visit to Florence! We were two couples, and the arrangement of the rooms made it perfectly cozy and private for each couple in our rooms. Also, the furnishings and bathrooms and well-equipped kitchen gave us everything we needed for a comfortable stay, and Costanza quickly responded to any questions or needs we had while we were there.
A couple of notes: The spot is about a fifteen-minute walk from the main sites; not far, but not so close that you can go home to rest between visits to one spot and another. The construction work, as mentioned in the other reviews, isn't an issue: It starts up around 7 a.m. and is done by 3 or 4 p.m., and it didn't take place over the weekend. However, the road noise other reviewers have mentioned isn't just during the daytime--it happens throughout the hours of the night when you likely plan to be sleeping, and it's loud enough to wake you up. I'd recommend bringing earplugs.
