I stayed at Gioacchino's place for about two months, as I was working on a project in Rome. It is a lovely place near Pigneto and very well connected. There is a direct tram/bus to Termini (central Rome) which takes 15 min only, and to Tiburtina station. The neighbourhood is extremely safe (I used to come back around 2-3 am on weekends, never had any issue with feeling unsafe or having questionable elements around the way) and the utilities are excellent. There are pharmacies, grocery stores, pizzerias, cafes, huge park, laundry services, ATM etc. within a 200m radius of the place.
As far as the room is concerned, the room is quite spacious with a very nice balcony attached to it. You live with three other people but your privacy is completely respected with no hindrance whatsoever. Everyone around the house is very nice and accommodating.
I would highly recommend this place to anyone staying in Rome.
