We can only recommend staying at Fabrizio’s!
He was always available for us and the apartment was very cleaned. The location is great 3 min away from Sisto Bridge in the heart of vibrant neighbourhood Trastevere, although in a very quiet street - so best of both - staying in a very cool and vibrant area and having good sleeping and resting nights.
If you are considering staying here, just book it! Won’t regret it!
