The place is exactly as described, but more spacious than the pictures suggest. The rooftop is a great added value to the place and the hosts are welcoming and extremely accomodating. The rain shower deserves a honorable mention too. Lisa and Alberto were very helpful to our request for Gluten Free restaurants (tip: Mama Eats is 10-12 minutes away and amazing!)
The only possible downside of the place might be that it is not that well connected to public transport, but if you are young and/or don't mind walking (like we did not mind walking) the place is a perfect hideaway to discover Rome that is within minutes from cozy restaurants in Trastevere, Piazza Navona, and the Vatican.
