Stayed here in room 13 for one night, was traveling solo before heading home to Philadelphia. The hotel is a two minute walk to Roma Termini, the staff was very friendly and gave me great tips for taking the train to the airport the next day. The room itself was very small and basic, perfect for a solo traveler, maybe a couple, the air conditioning was amazing, a great relief from the heat of Rome. I only wish there was a little suction cup style shelf in the shower to hold toiletries, I. had to sit my soap and shampoo on the floor since there was nowhere to sit in in the shower. That's the only negative I found about my stay, a very basic negative if ever there was one.
The staff brings you a small breakfast (juice, coffee/espresso, and a croissant) in the morning at a time of your choosing, that was a nice treat!
Overall, I would definitely stay here again if I ever find myself in Rome and want to be near public transportation.
