Sara and Marco are very nice hosts. The flat is located in a good area, close to the tube and other amenities (supermarkets, cafés, restaurants, ATMs) and within walking distance to the Vatican and the city center. You have access to your own private bathroom, and the room has a table and a fridge and other appliances, so you can have meals there. Overall it was a good experience and I'd recommend Sara and Marco's flat to anyone.
