Pretty easy to find and near the main train station. However, take note that the check-in is in a completely different street to that of the hostel apartment itself (a restaurant). Hostel is a flat (possibly flats) converted into room with communal area and two bathroom/toilets to share between three bedrooms. Bathroom floor always wet which isn't pleasant in the middle of the night . Could do with some air conditioning (rooms had aircon unit but didn't work), kitchen or at least fridge and some better bedding. Breakfast consisting of pastry and coffee/juice was included. I would recommend looking into accommodation with air conditioning before considering this place if traveling in summer.

Me and my family stay here overnight. The hostel is very near Roma Termini. But also very near restaurants and bars, so its noisy at night. I was barely able to sleep. The beds were squeaky and had bed bugs. Me and my daughter ended up with lots of bite marks. The lady who served the breakfast is not very friendly, we were treated like we were inconvenience to her own schedule... The bathroom floor is always wet, not very good drain and shower setup. We will not stay here again.

The family who owned the hostel were pretty nice. However, the beds were breaking/bowing in the middle, there was no air conditioning (Rome is HOT in the summer), there were no amenities such as a cooking area, common area, or computers. The street noise was incredibly loud as there is a bar patio underneath.
However, although a bit pricey it wasn't too bad for summer rates in the city. It was just a place to sleep - nothing more.

The hostel is a convenient 4-5 minutes walk from Rome Termini railway station. We stayed in a 4 bed private room (ensuite toilet/bathroom). The room was spacious, clean and comfortable. The reception staff was friendly and helpful. The breakfast is included which is an additional bonus.
