We've spent one month in Stefano's place. ideally located just outside the ring (ZTL zone) yet not too far by walk (there is the bus D a few minutes away that goes to the city and ends at the train station). You'll be in a quiet residential area. The WiFi is strong enough, making this place a perfect fit for people like us working from home while visiting the city outside working hours.
The hosts live above. They are discreet and professional (replacing sheets and towels every ten days in sealed packages). I highly recommend this place. Thank you for welcoming us!
