The number 1 feature of this hotel is just next door at Roma Termini, to score convenience points. To add more, because of its proximity to Roma Termini, food and drink choices are enormous. The room is big, the bed is comfortable and the shower is modern.
The downside is that the building is old and walls are not sound proofing: the guest in the next room is a phone chatter extremist: he is on the phone with at least 10 different people, from 8pm to the midnight, non stop talking and I was trying to get some sleep in order to get up at 5am in the morning, and I had no choices but to listen to his chatting for the whole evening.
