Alessandra and Gennaro are lovely and warm hosts, who made me feel very welcome for the two nights I stayed. They are responsive during check in and helped me find live music during my stay. Their flat is minutes away from Trastevere train station for easy transport, as well as to trams and buses. they're also located very close to Testaccio market and neighborhood. Their flat is breezy and clean, and the room and bathroom (you have your own) were very clean. Just note that if you like firm beds, the mattress may be too soft for your liking.
