The location of the place is just perfect - next to the Termini station and close to all the tourist destinations of Rome, though the area itself doesn't look that safe and a lot of homeless people nearby due to vicinity of the station. But if this doesn't bother you, don't hesitate to book it.
The flat itself is recently refurbished and very clean, it has two rooms and shared bathroom, no kitchen though, there is a microwave and a fridge in the corridor, but no sink, so if you need to wash your hands or anything, you can only do it in the bathroom if it's free and not occupied by other guests.
Overall, we enjoyed our stay there, good value for money
