We spent a nice weekend at Stefano's place, it was one of a few available affordable options in Rome at the time, and it was worth it!
The location is rather distant from the city center, but it can be reached with a bus and the bus station is nearby. It is a calm and quiet residential area with a lot of cats walking around :). You can hear birds singing during the day.
The apartment is best for 1-2 people, the bed is big and comfortable. The kitchen is well-equipped, there is a coffee maker and Stefano was very nice to provide us with some good snacks, coffee and milk. The plumbing fixtures are not in a best condition, but are clean and usable. And Stefano is always willing to help in case of any problems.
We didn't check the local restaurants, but there is a Conad supermarket nearby if you're in a mood to cook for yourself :).
