Riccardo's apartment is great! Spacious, right outside the vatican, and easy access to the city. We walked both days to the Colosseum and back. An hour each way, but very easy. Riccardo was very helpful with where to go and what to do. Make sure you eat at Goose! It was amazing. Sergio is a great waiter. We had some confusion with the bus stop, so just make sure you stop at Gregorio VII. Great experience in Rome!
