Overall this was a fine experience. Ours was a last minute booming, and the view is gorgeous and the location couldn't be more central. Cristina was very helpful and met us at the arranged time at the apartment, and when we did have an emergency she was able to be there in half an hour. The apartment was just as advertised (though it is quite cozy, you can sort of tell that from the listing, and difficult to reach once inside the building- there is a half flight of steps after the elevator, and we had a baby in a stroller- this might have been in the listing and I missed it).

The only real issues we had were: 1) the wifi is not reliable. It is shared amongst apartments (you join a network named after another apartment number) so it was spotty at best. I ended up going over my international data usage in three days because I would be on the wifi one second and then suddenly not anymore without realizing mid-email/photo posting on Facebook/etc. 2) though there is A/C it is only available during certain months and May wasn't one of them (it ended up being unseasonably cool anyway), and 3) Florence has mosquitoes (bring or buy spray, no matter what month) and there were lots of dead mosquitoes on the walls where previous tenants had smacked them and just left them. Short of installing window screens and repainting, it's going to be an issue for anyone.

The building itself is gorgeous, it is maybe half a block at most from the front door to the Duomo, and the terrace, though shared with three other apartments, offers a breathtaking view. If the wifi had been reliable, this would be a five star review.
