My girlfriend and me stayed two nights at Elena's place in the suburbs of Rome. Elena is a very welcoming and friendly host who makes you feel at home. The flat and especially the room are very nice. It's a 10 min walk to the nearest metro station which takes you in 20 min to the very heart of the city. Alternatively, there is a bus stop 100 m from the flat which links you to the metro.
All in all, we highly recommend Elena as a fabulous host.
