Very nice place to stay. A small independent guest house ran by very friendly and attentive people. I will definitely stay here on my next visit to Rome!
I travelled solo to work on a personal project. I needed something centric, clean, and reasonably priced for an 18 day stay. I booked it based on location, everything is within walking distance of the guesthouse.
I took the single room with a separate bathroom, I didn't mind it at all. The place is so quiet that I wasn't concerned for my privacy.
The only things I'd point out is that Hotels.com lists laundry as services and there isn't laundry available. And the room faces a back alley which can be a bit noisy at nights, especially during the weekends.
Other than that, the place is magnificent, they made me feel at home!
