We stayed at Mimmo's place for three nights. The bedroom was clean and has a large private bathroom connected to the bedroom (with a washing machine!). We arrived by car after driving through Tuscany, and Mimmo was very responsive and helped us navigate check in as you cannot drive in most of the city center (and you definitely do not need a car once you are there). The location was great, a very short walk to the Duomo and walking distance to everything in the historic center. Even though we stayed in August, the weather cooled down a lot in the evenings and we slept comfortably with the fan and windows open and did not need the portable AC. Mimmo also provided many good recommendations for places to eat. We had a great stay!
