We had excellent stay at Maurizio's place. This is a very large appartment, cozy and convenient. The apartment is clean and quiet. The surrounding is very nice: there are good restuarants used by locals, few small supermarkets and good market with selection of food and clothing "Mercato Testaccio" (We had excellent shopping of branded clothing and shoes for very less price, as well as for local food and wines).
Maurizio is very pleasant person and I would definitely recommend his appartment. We have enjoyed our stay in Rome.
