We had a really nice stay at the apartment. It was clean and spacious and fit our needs perfectly. We did not meet Cristina but her mother met us when we checked in (we asked for an early check in which Cristina agreed to without hesitation). Her mom gave us great tips about where and what to do in the area. Cristina responded quickly to a few questions we had. That was greatly appreciated. She arranged for our cab ride to the airport.
As others have said, the apartment is in a residential area, 10 minute walk from the Vatican and a 30 minute walk to the major attractions. My wife and I are walkers and we felt safe when returning back to the apartment late at night. The apartment had all of the kitchen amenities you would need to cook meals, which is a treat compared to other Airbnb's that we have stayed at. All in all we had a really nice stay. Thanks Cristina.
