I stayed at Stefano's place with 8 of my friends during new years. He provided me with maps and info about Rome through email. That was very helpfull. He picked us up at the trainstation and showed us the appartment. Everything we needed was there. Kitchen, towels, washing machine, bbq, enough beds and sheets and even a nice welcome gift :)
The place was great and one time stefano and his wife cooked us a very very nice Italian dinner.

The only thing i can say is that if you want to go out a lot in Rome it takes you about 1 hour to get from the center to the appartment because you have to take the night bus.

There is a busstop 5 min from the apartment. The only downside about that is that there is no busschedule in Rome. So sometimes we waited longer than 30 min for the bus to arrive and it takes you a little bit longer to get to the center.
But once you get in the bus, you will be in the center within 30 min. So not to long.

It's a great and cheap place if you want to escape the city rush and if you have enough time on your hands the bustimes wouldnt be a problem.
