Our stay has been very lovely ! The host has been available for my questions and always answers very quickly. The appartment is the same as the picture : small but very nice. The location is perfect : near the Trevi Foutain but also not far away from Piazza Venezia and the Pantheon. We did everything by foot no need to take the metro :)
PS : do not eat at the small restaurant just near the appartment, it is expensive for what it is and not really good. There are better places in Roma !
