My friend and I stayed with Alessandro for 3 nights and it was one of the best experiences ever. When we arrived to Alessandro's he had maps laid out for us and went over all areas of Florence that we should see. He also had bus times available for us so that we didn't have to wait at the stop. We arrived in Florence a little before we were suppose to check in and he pointed us to the market area to grab a glass of wine and some food. He also gave us on recommendations on great restaurants, and the night life area as well.
The room was very clean along with the rest of the house. He provided clean glasses that we could use for water, wine, and coffee along with towels. I highly recommend Alessandro and if I'm in Florence again I would most likely try and stay with him again.
