My son and I stayed in Antonio's apartment and can highly recommend it. It's in a great location (both being next to the Colosseum and steps away from a subway station), has ample space for two people, and the AC blows nice and cold. The courtyard outside was really nice but we didn't end up using it much. There is a washing machine in the courtyard that you can use to wash your clothes (just bring your own detergent). Everything was exactly as described and I would definitely consider staying here again next time I am in Rome.
