Small but comfortable flat, perfect for a couple that want to visit Rome. The bedroom is large, the kitchen is full equipped and the bathroom is huge (there's also a 1.6 m bathtube!). The metro is at 5 min. walking, so you can reach the very center of Rome (Colosseum) in less than 15 minutes. Around the flat, you can find a very good supermarket at 3 min., and in 10 min walking you can reach Piazza Bologna, one of the commercial areas of Rome, full of every kind of shops, bars, pubs.
Last but not least, I'm roman, I know quite well my city and it's history and monuments and, if you need, I can advice you on places to see, in or out the canonical touristic itineraries, how to travel with public transportation and where you can find the real roman dishes (and not the touristic menus).
