Cristina's apartment was perfect for us! It is in the Monte Verde neighborhood which is a nice residential area. There are shops and restaurants nearby and some nice parks too. It is new and nicely decorated and has everything you need for your holiday. The washer/dryer unit worked well on washing and drying our clothes. There is a bus stop about 2 minutes away by walking (Bus 44 I think) and we could take that bus to the stop for Tram 8 which would take us into Trastevere for some good Italian food.
Cristina was also very nice and personable. She is a great host and she met us at the apartment at the agreed up on time and showed us around. I would definitely at her place the next time I am in Rome.
