My mother and I rented the apartment for our trip to Rome to celebrate her 70th Birthday and retirement. The apartment was suited perfectly for this purpose. We each had our own bedroom and connected bathroom. Her bedroom had a single bed with views of St. Peters, and my room had a queen size bed.
The deck was fantastic, we frequently dined and relaxed out there. The kitchen was well appointed for making breakfast or a simple lunch, but probably not suited to make a complicated meal (we ate out each night, so not a problem for us). There was also a 24/7 market conveniently located a block away which was great, and some good restaurants nearby.
Our host Linda was super accommodating, meeting us for a mid-morning arrival and even arranging for airport transportation.

The location was a bit different than we expected. St. Peter’s Square was about a 15 minute walk, and the nearest Metro location was about a 25 minute walk. There is a bus stop that heads in the “right” direction a block away, but you will first need to get a pass. A cab ride to the center of city was 10-15 Euros. Fortunately we had great weather and enjoyed walking so everything worked out great.
