Our stay by Sonia's place was excellent, the apartment is very clean and has all you would need, very cosy and warm, perfect for 2 couples. Lovely! Both Sonia and Paolo were very helpful with any kind of information that we needed and helping us with the transfer from the airport by booking us a car. The area is actually very close to the Vatican walls, it was a pleasure to walk to Piazza San Pietro. The metro station was 5 minutes walk away indeed - very close, and the bus station is right in front of the building - which makes transportation really easy.
