Mauro's place was as good as the photo described.
Its clean and cool in hot summer day in Rome.
And you have everything you need in the room.

You will walk like 15 minutes to the Trastevere train station.
And from there you can take train to city center or to Vatican city ( 2 stops).

And the area is safe,
and I was walking there around 11 pm,
and still see many people outside hanging out and eat foods :)!
