Caterina & Patrizia's place is located in a great neighborhood. It is a nicely appointed apartment with tons of space for our family of 4.
For anyone with kids (especially 2 teens) the icing on the cake is the 2 bathrooms.
From a location standpoint, the major tourist attractions are all within an easy 30 minute stroll. However, the Metro station is only a few blocks away so if you're there during very hot weather, it's a great option to walking for getting around.
