This is a very unique rooftop apartment - with windows on three sides bringing awesome sunlight into the studio. We loved the private terrace and view of Rome but it was too cold to spend time outside during our visit.
The studio is pretty compact but fine for two people. As others have mentioned it is modestly furnished and could use some upgrades but there are just enough amenities for cooking at home. The bed is very very comfortable and even though Trastevere is a popular neighborhood for nightlife the apartment was quiet.
We would definitely recommend, especially for warmer months so you can take advantage of the terrace!
