Manuela's house is clean and beautiful, but more importantly her family is very warm and welcoming. I felt at home in Rome. They kindly invited me to join them for dinner, beat experience I had in Rome!
Manuela is quick with responses and has great tips on sightseeing (also lookout for a small green diary in the room which has various business cards of recommended shops/restaurant/bars).
The house is in a quiet and safe neighborhood, with a great local restaurant just 10 steps away, and a big supermarket just 1min away. Note that it takes about 45mins via public transport to reach most tourist sites, but the public transport is easily accessible.
I would highly recommend her place
