Great pick, great host! Serena was lovely and really knew how to make you feel at home away from home! She offered to provide us a round trip ride cheaper than most other options to/from FCO airport. Good idea if you want some good tips about the city and what better way to get to know your host?
The flat is situated in a quiet area tucked away from busy traffic and the masses of tourists. The flat is located only a short walk(30 mins) or bus ride from the Vatican city. You can practically catch a bus which will take you to all the major points in Rome. Around the flat you can find a ton of places to eat good local food. There are a few supermarkets near the area in case you rather cook a meal and save some cash.
I’d definitely recommend Serena’s place if you’re coming to Rome.
