My experience in Ro's place was the best! The room is even better than described, very big, with lots of light and the bed is very comfy. The apartment in general is gorgeous and clean. If you are a walker like me, you won't need public transport because after a 15 minute stroll you can be at the city center! Besides, Trastevere itself is a great area to spend time in if you don't want to commute much. Also the bus to Termini right down the building! And well Roberta is just lovely. She is kind and helpful with directions and advice, as well as her friend Giancarlo. Beautiful people. I would definitely come back and stay at hers again without any doubts
