Piero was very helpful! First, the directions he gave us to get to his apartment from the Roma Termini station was easy to follow. The apartment is walking distance to the Vatican. The flat was very nice and clean, it has internet and cable so you will never be bored when you are home. Another got thing is the apartment was so close to the supermarket! (it's just literally downstairs) and the bus stop! I highly recommend Piero's place and if I go back in Rome I will probably check in with Piero again!
