STAY HERE. You can walk to anything in Rome you want to see and then come back and be right in the middle of the best food and nightlife the city has to offer. I wouldn't recommend it for more than two people, as the bathroom is off the bedroom and there's not a lot of privacy. The kitchen is small and not really that usable, but you should be out eating pasta alla carbonara and osso buco anyway! We were in Rome for 5 days and didn't take a cab once except for to/from the airport (there's a cab stand around the corner if you do need one). Just walk down the street and across the river and Rome is at your fingertips. The street is full of activity but the bedroom is in the back of the apartment, so it's actually surprisingly quiet to sleep in if you close the door to the bedroom. We loved this place!!!
