Frederick is the best host we've ever had. We were a family of 10 people. He helped us carry suitcases up stairs. He left us food and drinks. His house is absolutely beautiful with paintings he has done himself and gorgeous Florence style floors. The house is in a great location, 5min walk from the train station and the duomo. Even though it's in the city center, it's very quiet up at the house. Also, super close to grocery shopping. I think he is in the process of increasing the electricity wattage usage so it really is perfect. Again, best place to experience Florence and a very kind and friendly host.
