Mattia's apartment is a perfect place to stay if you are visiting Rome. The flat itself was clean, spacious and had a big balcony as well as being in a good location (10-15 minutes away from train station and colosseum).
Mattia was a great host, making us feel very welcome with breakfast in the morning.
Would definitely recommend staying here if you are visiting Rome because of the great location, good prices and the amazing host!
