Some pros:
-Within 10 min walk to both train stations (airport train and metro), it's only a 10 min metro ride to termini which is the main station and about 45 min to the airport using the Roma Ostiense station
-Location is quite safe - never had any problems when walking home from the train station even at 1AM
-Nice, big bed
-The owner is very friendly, stayed up until midnight to meet us, told us about things nearby, was happy to help with anything we needed
-Air conditioning was new and worked very well (a must for the summer)
-Water pressure is solid
-Breakfast place is right next door, has great croissants and very friendly staff
-Wifi is generally quite good, much better than any chain hotel I've ever stayed in
Possible improvements:
-No hooks/ledges in the bathroom for your stuff
-The TV was 13 inches and old school
-The washroom "door" is a slide across
Overall a good place to stay and a place I'd stay again. It's a good place to be with an intimate partner, but if you're a couple of friends then it's probably not ideal as you'll hear everything from the bathroom.
