We stayed here for 3 nights recently. It is such an excellent location. Particularly if you want to see historic Rome. It is across (literally) from the Forum Romanum, around the corner from the Colosseum, right by the old palace (Palentine), beside the old Circus Maximus and across from the Aventine hill. San Clemente (excellent and maintained by the Dominicans now) and San Giovanni in Laterno are a short walk away (San Giovanni is a little longer but worth the walk).
A 15-20min quick walk to areas closer to the Vatican. Best to get a cab or underground (which is surprisingly easy to get around in for a tourist). Hotel is a good standard, clean, friendly and attentive staff. I would certainly stay here again - and will. When you get a solid hotel in Rome you remember it! Thanks to all the staff... loved the welcome glass of prosecco and the restaurant recommendation around the corner was spot on!
I would say good for couples (we got engaged!) but friends, families etc. should love the place and location.
