We really enjoyed our stay in Grazia's place.
The apartment really felt like a home. Very cozy and well equipped. Also the very warm weather wasn't bothering us because of the two air conditioners; very nice (:
The apartment was located at a pretty good spot. Florence is reachable for walking distances so you could reach all the highlights if the city by foot and come back to a quite and nice neighborhood to sleep (:
So I would really recommend this apartment!
