The appartment of Stefano is everything you wish for when visiting a city like Rome. Clean, bright and plenty of space for two couples, with the big advantage of having your own bathroom per bedroom. The location is excellent, with bus 46 stopping just around the corner and St Peter within walking distance of around 10 minutes.
Some excellent restaurants (Goose and La Caletta) within 60 metres and a supermarket within 200 metres are ideal. If you're a light sleeper, you may find the streetnoise during the night disturbing, but after a day of walking through the city you're so exhausted that you hardly notice anymore.
Stefano Celi is the perfect host, he responds very quickly to every text message and is always there to help you with any question you have.
I could not think of a better place to stay.
