We found Rosanna's house very easily and were welcomed by her husband.
Each bedroom is rented out to different people on airbnb. It was nice to be able to make friends with the other guests. There were two bathrooms which was useful as there were many guests in the house.
The bedroom was very spacious (4 single beds) and clean.
The wifi worked well but we got a better signal near the door.
The kitchen was well-equipped which made it easier to cook our own meals.
The suburb of San Lorenzo is very nice with a local vibe, affordable restaurants and friendly locals.
I highly recommend this airbnb and we would return if we come to Rome again.
