We stayed in this spacious, stylish apartment with our 2 children. Matteo is an amazing host, with great local tips and recommendations. Everything is provided, maps, wifi, air conditioning, lots of pillows and clean towels. The apartment is on the ground floor so there is even a outdoor courtyard. It is in an amazing location, just 5 minutes walk to the Colosseum and the Colosseo metro.
I would highly recommend Matteo's apartment for your stay in Rome.
Note: there are some steps in the apartment and the bedroom is on a mezzanine level. This wasn't an issue for us but just be aware if stairs are difficult for you or you are staying with very young children.
