We had an incredible time staying in Florence at Gian's apartment. The place is close enough that the central city is a ten minute walk--the Duomo, Ponte Vecchio, the Palazzo and more--but also off the main tourist path enough that you get some breathing room. There are a handful of nice bakeries and grocery stores nearby, and some great restaurants that Gian left recommendations for.
The apartment is as beautiful as it appears in the pictures, if not more so. Very clean and modern, also very cozy, and the bed is VERY comfortable. There's a significant amount of street noise, but nothing too out of the ordinary and it didn't bother us much. The kitchen is also great, and we prepared a couple of dinners with ease.

Gian was also very helpful and check-in was carried off without a hitch. It really felt as though we got an amazing deal, considering how little we paid for such a comfortable, centrally located apartment. We would ABSOLUTELY stay here again, and recommend it to any friends looking for a place to discover Florence!
