I really enjoyed my stay at Stefano's. It It was very convenient for the Vatican and sightseeing, the ensuite / shower was great, the place immaculately clean and the price very fair. Stefano was good at communication and helpful.
I did have an issue with noise from the neighbour who are opposite E.g. their dog barking in the middle of the night. I would suggest bringing earplugs if sensitive to noise like me.
