Fabio’s place is honestly great value for what you get. The place is literally adjacent to the office of the official tour of the Colosseum and minutes from the Tevi Fountain. You’d be hard pressed to find something in a better location if you’re there to tour. As others have mentioned the shower is prone to leaking into the bottom floor kitchen so watch out for that. If you book this place you MUST check out the restaurant “Ristorante la Nuova Piazzetta”. It’s literally 10 steps from the building and we found it to be one of the best places to eat in Rome. Overall, if location is important to you - this is the place!
