Host was wonderfully helpful and responded within a reasonable time when questions were asked of him. The apartment is spacious, close to various bus stations, tour group offerings and the metro. The Vatican museum is literally around the corner and across from it is a wonderful little coffee shop. A carrefour express supermarket is literally outside the door of the condominium building and an even better stocked supermarket is 200m down the road (if it is even that far). Accessible by lift (although there is 4 steps to get to the lift, but easily manageable).
Would definitely recommend.
