Check-in was super easy. Carlo met me at the apartment and showed me around the place. My train was a little late getting in, so I ended up arriving right at 8pm (the very end of their check-in time), which Carlo was super gracious about. (Be sure to contact Beatrice and Carlo with your arrival time, as they don't live in the building and will have to drive over to meet you.) The apartment is in a great location; it's just a short walk from S.M.N. train station and the historic center of Florence. The area was quiet, which is kind of incredible since it's in the middle of a big city. The apartment itself is simple, yet suited my needs perfectly since I was only there for the night. If you're only in Florence for a short time and want to be close to its main attractions, I definitely recommend staying here!
