We stayed for 2 nights and the location was perfect!
Grocery store is 2 blocks away, really close, with a good selection of fresh produce, meat and premade dinners (if you don't want to cook)
The bed was very comfortable and we also tried a pull-out couch in the living room - it was not bad at all. Check in and out was easy. We took a taxi when we arrived to the train station and walked back from the apartment (10 minutes) when we left for Milan. Florence is full of friendly, happy people and we loved every minute of been there.

Thank you, Paola
