My wife and I spent a great few days exploring Florence and this was a great base. Silvia met us and gave us some great recommendations of places to eat, drink and see. She was lovely and extremely helpful.
The apartment itself is lovely. The ceilings are low, but really it adds to the charm of this super cosy place. Everything is comfortable and feels extremely homely. We cooked a couple of times too and the kitchen is well equipped and good to use.
Location-wise, it's a great combination of close to everything and slightly out of the way. You can reach any of the sites in 5-15 minutes walk, but your front door isn't swamped with people.
Overall, one of my favorite places I've stayed.
