My wife and I stayed for 5 days. The location it can't be better. It is in the very heart of Trastevere, and we just had to go outside to be in THE place to be at night. Near tons of bars, restaurants, gelaterias, it is an awesome place. Clelia was very helpful, and a great host.
It is not very spacious, but for the location it will be all you need when in rome.
