Ortensia and her husband were very kind and helpful. The rooms with the kitchen are great, and it's really pleasant to sit at the terrace and enjoy breakfast in the morning. B&B is situated near Trastevere station and it's good location, especially for those who's going to arrive/leave to/from Fiumicino airport.
It's not so difficult to reach historic centre of Rome from here and you can find many bars in the night near Trastevere neighbourhood.
I can recommend these rooms for everyone who's planning a trip to Rome, and I think it's one of the best B&B's that I have seen.
