Lis Mari is a wonderful host! My boyfriend and I had a delayed flight and Lis stayed at the apartment to meet us and make sure we got there. She gave us a list which recommended things to do throughout the city as well as directions on how to get there and back. We would have been lost without that list! She also left us a bottle of red wine as a greeting gift! A wonderful first night.
The apartment is out of the tourist areas at the entrance to the biggest park in Rome, Villa Doria Pamphili, which was one of the most beautiful places that we visited in Rome. If you stay here, just wander the park for a few hours and you'll be amazed at all the buildings you'll find. The apartment is a stone's throw from public transportation (buses) and we were able to navigate the city easily from there. We were very pleased with our stay.
If you are very tall like me (6'6"),just know that the bedroom itself has a ceiling which is quite low and made for some funny pictures. However, don't let this discourage you. The sofa bed in the front room sleeps 2 and is very comfortable.

p.s. - The gelateria (Pinguini?) up Via Zambarelli from the apartment was some of the best we had throughout the city.
