We stayed at Vincenzo's place two times when we were visiting Rome. We were visiting Rome for the first time and we felt like we're at home thanks to Vincenzo's hospitality. He helped us with the taxi arrangement from the airport, gave us great tips for the city and even had prepared a day tour suggestions.
The apartment is clean and very spacious. It's located very close to the Vatican and it's just 5 min. walk to the train station.
I'm recommending Vincenzo's place to anyone visiting Rome!
