My friend and I had a really nice stay at Brittany's loft. The apartment is spacious, neatly kept, and centrally located. We were able to walk to all major sites around Florence with ease. Jeffrey met us, despite our late arrival due to plane delays, and kindly showed us spots to go around the area (cafes, groceries, gelaterias, etc).
The apartment is equipped with Netflix as well (for days we wanted to rest a bit). My only complaints would be that the shower is a bit small (even for someone my size) and the stairs are cool, but you should definitely be very careful walking up and down!
Overall, enjoyed our stay a lot. Recommend!
