The room is nice, but small - only for sleeping. Clean end comfortable beds, interesting architecture. Kitchen well equipped and very clean dishes.
We didn't meet Simon at all but met his very helpful and friendly brother - Emmanuel, who really went all the way to make us feel good and help in every possible way.
The apartment is short walking distance to the river and to Trestevere and to Metro (Pyramid st.) and some buses. A nice local neighborhood with bakery, ice cream, supermarket and pizzeria on the same block.
Important to notice that the kitchen and living room are public to other guests and that Emmanuel, his father and some other family members come there on a daily basis so not much privacy.
