To stay in Massimo's apartment was the best decision. It's a 10 minute walk to the Vatican. It has a "Carrefour" (supermarket) quite close too. It's also very very close to a subway station that is 15 minutes away from Roma termini. One of the best pizza places is very near too (Bonci). So for every pizza lover, Massimo's place is the best. And it is worth to mention that my girlfriend's birthday was one of those days and Massimo had the detail of leaving us a gift the day we arrived so that we could celebrate that day. Very kind of him. ¡Thanks Massimo! ¡Hope to come back soon!
