I loved this place so much last year that I returned. This is the most adorable well to do apartment in the best location. I spent 4 days here the first time and rounded out my experience in Florence with 3 days here this go round.
I was so thankful for the generosity of the host. Not only did they provided great suggestions on what to do, but they booked dinner reservations for each night we stayed at phenomenal restaurants. They also had snacks, bathroom necessities, and laundry detergent, along with a cold bottle of water among their other amenities.
The apartment is on the 5th floor but there is a lift that takes you up 4 floors. Daily I walked the stairs just because of how much I was eating. The neighborhood is quiet but is right in the thick of things at the bridge.
You can easily enjoy the city center or the Oltrarno. There is no question I will book here again when I return to Florence. I highly recommend you do the same!
