We loved our stay at Adriano's place. His mother checked us in. She was so lovely and explained to us how everything in the apartment worked. She also gave us a map of the area which showed restaurants, supermarkets, bus stops, etc.
We walked everywhere - down the hill to trastevere and across the river to the main tourist sights (Colosseum, Trevi, Roman Forum, etc). We would love to stay again next time we are in Rome.
