For participation in a conference, I and my wife stayed in this private room for 5 nights.
There was only a few meters distance between our room and the railways terminated to Roma Termini !!!, so it was very much noisy even after midnight.
The apartment was in the 3rd floor, but the elevator was out of order.
The bathroom was private, but the shower was very small and its faucet was hard to adjust. They make the shower so uncomfortable.
The host lent only one set of keys; it was an inconvenience to 2 persons, especially for staying longer than a day.
Actually, we chose this accommodation because of kitchenware availability. But, kitchen was in another apartment, so we needed to open and lock several doors for using the kitchen every time. Moreover, the kitchen itself was organized in 2 separate rooms; cupboard in one room and table in another. It makes the kitchen uncomfortable.
The host was responsible, but I think a lot of better accommodations can be found in Rome, near to city center, at the same price. All in all, I did not recommend this one.
