Fabio's apartment was perfect for 2 adults. It looks exactly like it was described.
Fabio allowed us to check in earlier (actually 9 am) as the apartment was prepared for us in the previous day. We found a bottle of water and some sweets in the fridge. But most important for us was the coffee left and we did not boder to take care for it in all mornings during our stay.
However, the best feature of the apartment, by far, was the location. Me and my wife spend five days in Rome and we never used any transport. The main places (Coliseum, Vatican city, Borghese gallery and many more ) to visit are reachable by foot. There are many small restaurants in the area as well.
The bathroom is a bit small, but it was OK for me (1.83 m) and it is clean.
I will definitely recommend Fabio's apartment.
