We stayed 5 nights at Tommy's Campo studio apartment and had a wonderful time! The unit was exactly as described and clean. The position is ideal, very central to all of the major attractions, or transport to them. There is a wonderful bakery around the corner and a fab Trattoria only a few streets away. There is also the Campo di Fiori itself, of course! Just a block away. The unit is very quiet and the upper floor location gives a great view from the windows. There are several flights of stairs (as there are right across Rome!) but Tommy very graciously helped with our luggage. Tommy was an excellent host, friendly and professional. We would have no hesitation staying here again and would highly recommend this unit. We would also recommend you print the location map inluded on this website so you can find your way back after a long day of sightseeing, without resorting to Hansel and Gretel measures :)
As the appartment is within walking distance to everything (except perhaps the Colesseum), make sure you take walking shoes you are used to as the cobblestones in Rome are unforgiving!

Book this and enjoy your trip!
