We had a very good time in Rome, in the comfy Enrica's B&B ! Easy to get in, in a quiet (but living) neighborhood, not far from downtown, close to the public transports and well organized (check-in and check-out, breakfast, etc.) The room was very nice, comfortable and clean, and Enrica was always available to give us informations !
It's a great place to settle down if you want to see most of Rome in a few days :) and even meet people at the B&B !
I definately recommand Enrica's place !
