First time in Rome, this is probably the cheapest room I could find, but the place sure is very nice and clean to stay. It surpasses the quality you would expect at that price level.
The surroundings at night makes you feel uneasy, since the street aren’t very well lit. If you manage to get there during the day and leave your stuff, then I would totally recommend to anyone to not think twice and stay there. This is a place I would come back again without doubt.
