We were met by Maria's housekeeper who was very nice. She got us settled in and made good recommendations for places to eat. The apartment itself is really nice and neat and has everything you would need. It looks exactly as pictured.
The location is perfect, in a quiet mostly residential area. It's pretty much in between Vatican city and the Colosseum, so if you like to walk then you can get anywhere by foot. If not, Maria provides extensive information in the apartment on all forms of transportation (including the tram, which stops close to her door). Be sure to look at the booklet she put together because there's lots of helpful information.
We had the best pizza ever just right in front of the building (open only for dinner) next to the tobacco shop. Sorry but I can't remember the name.
Although we would like to have met Maria in person, she made sure everything was taken care of and was easily reached by email.
We had a wonderful time in Rome and Maria's apartment was perfect for our stay. I would definitely recommend her apartment!
