Antonio was very accommodating, polite, and friendly. The room was spacious and clean. His place was a five-minute walk (at most) from the train station and near many main attractions (Academia, Duomo, etc.). My friend and I showed up later (around 10:30 pm) and he had no problem letting us check in at that time. He also checked in on us each day to make sure we were doing well and if we had any questions about Florence in general. I highly recommend Antonio!
