Wow! What an amazing place! We initially thought we wanted to stay more 'central', or towards the Trastevere area, but the location of Vincenzo's place was what we loved the most. It's maybe 5 minutes from the train station, and is a great residential neighborhood that we felt right at home in. Out of our three nights in Rome, we ended up staying in the neighborhood and enjoyed having drinks and dinner at outdoor bars and restaurants.
I hope to come back to Rome someday, and would be so disappointed if I couldn't stay at Vincenzo's.
