On arrival, Valerio was very friendly and helpful, giving us local advice and giving us a tour of the nearest supermarket/metro station/quickest way to the Vatican museum and best nearby restaurant. The apartment was spacious and decorated in a modern and high standard. The kitchen was a pleasure to use, and basics like olive oil/pasta/tea were provided for our use.
The apartment is a couple of minutes from a large supermarket and metro station, and a 10-15 min walk from the Vatican Museum entrance. In our 6 days we took the metro into the city twice, and walked the rest of the time - by the time you take in the sights, it doesn't take long to walk into the city. Really glad we booked to stay here!
