The apartment is in the best location in Trastevere. You can go out and immediately stroll in this beautiful, young and vibrant neighbourhood.
The apartment itself is brand new (we were the first visitors) and everything was designed with great taste and very high standards.
The apartment is huge - a big living room with 2 sofas, a large and well-equipped kitchen, and a nice bedroom with a great bed, and an awesome outside garden that is private and accessible only by you.
The photos really don't serve this place right - it's much nicer in reality (even though it is really nice from the photos).
Daniela was really nice and allowed us to check-in early and check-out late (since there was no other reservation for that day), which we really appreciated as our flight was later that day.
Note that the apartment itself shares a wall (of the living room) with the outside of a small restaurant. It didn't bother us at all since by the time we went to bed the restaurant was already closed, but it may concern some people. The noise was not bad anyway, and in the night it is completely silent in that area.
