I just celebrated my 30th bday with my best friend. We live in different countries and we chose Rome for this summer's meeting :) Great choice indeed!
Maurizio's flat is really nice - great location, clean and ordered, and has many books and DVDs.. in case you'd stay inside for the evening :))) hopefully you won't, as it is 10 min walk to the Colosseum and 30 min walk to Piazza Navona (one of the biggest and coolest squares in Rome).
Communication with Maurizio was great from the beginning and he explained to me how to get to the flat form the airport. We shortly met the first day, he explained how everything works and left me the key, but he was available for our entire stay in case we had other questions. We had a great stay in Rome. I strongly recommend Maurizio's place!
