We stood at Chiaras apartment 4 nights. The apartment is about 15 min away (on foot) from the train station Termini. The station of the bus no. 71 was 5 min away from the apartment. The room was clean and cozy. In the evenings you could hear the noice from the street (partying students) but Chiara provided us with earplugs :)
All in all we recommend this room:) And Chiara was very nice and answered our questions very fast.
