Diletta's flat is in fact a cabin built in the building's courtyard. Some parts are a bit used (the floor surface, some lights flickered) and could benefit from a refreshment but everything was particularly cleaned.
That being said it's especially well decorated and furnished. It really gives a "home" feeling. The bed is extra comfortable and Wifi access is very fast at 70 Mbps (important if you want to work from there).
The exterior area was particularly appreciated as we had nice weather during our stay and we took our breakfast and meals outside. Sometimes, therer were many mosquitos but Diletta provided protection against them.
Location is a bit far away from centro storico but in a very pleasant area (Aventino Hill). Restaurants and services are just below the hill in the Testaccio neighborhood (5-10 mns walk) where there is the best pasticceria in town: Barberini! Buses connect this area to city center and old town (about 15-20 mns). On the other side of the hill, Piramide and Circo Massimo subway stations are only 10 mns away by foot.
At last, Diletta is a very nice person. She was waiting for us late at check-in, was very responsive, and answered quickly to all our questions.
Overall, it was a nice stay and we would recommend it for other travelers, especially for workers and long stay and during the nice season.
