Vincenzo is a very friendly Italian man. He replied all my messages very quickly, and gave me a lot of tips on typical Italian restaurants. The location of his flat is amazing - walking distance: 1 minute from the Vittorio Emanuele station, 8 minutes from the Roma Termini station and 13 minutes from the Colosseum. The flat is very spacious and clean. I will definitely be back and I hope Vincenzo hosts me again :)
