We had a very nice stay at Raffaella's and would reccomend this apartment to other people. Raffaella was responding quickly to our questions/concerns and even arranged for a 'blue car' (for an additional cost) to meet us at the airport, and take us to the apartment. She met us at the apartment, where she gaves us instructions and provided us with some maps of Rome.
The apartment is located in the outskirts of Rome but conveniently close to the line 2 tram stop, which takes you immediately to the metro stop Via del Flaminio. From there you can take the train to all sights and even walk to a few of them.
There are a number of bars and restaurants located on the main road, as well as a great bakery. Everything you need is pretty much there, even a pharmacy.
If you are looking for an inexpensive but easy commute location, I would highly recommend this place.
