Letizia was a great host, and she even arranged a taxi to the airport for the morning of our departure. Accommodations were as advertised and the location is unbeatable, being a very short walk to the Vatican north entrance. The street noise was low (especially for Rome), and there were many decent restaurants within a quick walking distance. Safe and secure building, and we felt comfortable walking around the neighborhood after dark.
The only (minor) issue was that the floors could have been cleaner, and we chose to wear shoes to walk around the room to keep socks clean. This may simply be a difference between European and North American standards.
I would recommend this property for anyone who wants to focus on exploring the Vatican area in particular. Good value for the dollar.
