Really enjoyed my stay here! It's not the most modern of places, but it did feel "authentic" with its surroundings. Lots of room for 3 people, I stayed by myself. Washroom is a little old, but it gets the job done.
It's about 15 minutes walk from the central station, Termni but there are frequent busses/street cars that take you there as well as to a subway stop.
Just a tip if you're staying in Rome, and you are walking alot/bussing, google water fountains and you can find public water fountains located across the city to refill your bottle.
