This hotel is a good, basic guest house/hotel. It's close to the metro and major Rome sights. It's quiet at night, clean, and has a small breakfast to get you started in the morning. Air conditioner, shower, mini fridge all worked fine.
It's fairly easy to find as long as you look for the address and not a sign (there is none).
The only con is that the desk is not staffed for much of the day (or at least it varies). The man at the desk is quite helpful though.
