Davide's place is awesome for a solo traveler or couple. The location is awesome - you're right in the heart of Florence! Everything was a quick walk away, making it a great home base for me and my fiance. The apartment was cozy, and the kitchen had every cooking implement we needed. But the best part was Davide himself! He sat us down and gave us all his recommendations on what to see and eat in the city. He even described what local Tuscan dishes we should try - with pictures! I have never had such a helpful host.
The only caution I would have is for very, very light sleepers - you can very faintly hear the bustle of the city and the ringing of the church bells through the windows when they're closed. It didn't bother us at all, but I could see how a troublesome sleeper might have problems. And as mentioned in the listing, it's up four flights of stairs. No problem for us, but those with limited mobility would have trouble!
