We enjoyed our stay at Federico's place very much. The apartment is the perfect starting point to discover Rome. I was there with my two children for 5 days and we were able to reach almost every sight within a max 30 minutes walk - perfect if you are travelling with children. The apartment is very tastefully and lovingly furnished and very clean. The bathroom is small but fine and the kitchen very well equipped. The children loved the long spiral staircase to the kitchen in the basement as well as the "secret exit". The second double bed is in the spacious kitchen in the cellar, but we didn't need it, because the three of us stayed well in the bedroom upstairs.
In Trastevere the night can be quite busy but the appartement is located in a small and rather quiet street. We have appreciated the surroundings with many restaurants, ice cream shops and bars very much.
Federico and his father were the best hosts you could wish for. The communication in advance was perfect and exceptionally friendly. Our late arrival as well as the very early departure were no problem at all. Many thanks to Federico for the flexibility and the warm welcome (with snacks, coffee and water. We felt good all around and will come again with pleasure.
