Excellent location. It is only a few hundred meters from to the Roma Termini train station.
The shower screens were dusty and moldy. The air conditioner in the bed room has its days and should be replaced by new one.
At night time, a number of people gathered outside the main entrance and drunk. During my stay, there was no major hassle happened but I did feel unease every time when I pass through these groups of people in order to access the entrance.
Hosts were good and they were responsive to my comments on the check-in process by the unexperienced staff. Check-in staff was on time though.
