Great place to stay. The terrace is super. Sunny in the mornings, shady in the evening. The kitchen has every thing you need and 2 espresso makers. Very, very clean. The Supermarket is close by and the station is as well. 20 minutes walk maximum to St. Peter's. Tips? Get 'mytaxi' app and connect to paypal. Also the 'Lonely Planet guide to Rome' which offers great place to eat and drink based on your location. Book Cistine Chapel tour well in advance and if you come out of the door top right you come out in St.Peter's.
