I was staying at Maurizio´s place for almost a week for working reasons. It is very good located if somehow you need to reach the university Roma Tre, the metro is just 2 minutes by foot and you can easily reach all the touristic opportunities.
Nice and calm area, the house is clean and has everything you need. One thing I would maybe mention is that you can hear the neighbours constantly, the walls are not thick enough and somehow is funny to hear their conversations or when they cook or take a shower. In any case, I was not spending much time inside the apartment because I had to work and in the night is calm again.
I can totally recommend to stay at Maurizio´s apartment! He is very easy to communicate and helpful in anything you ask him. :)
