Very good experience overall.
Its more of a hostel-like experience, which was perfect for us.
Private room and bathroom, and a shared well equipped kitchen.
The location is like described, in a less comfortable area, but had a couple of supermarkets (asian and local) very close, in addition to a nice cafe around the corner.
4 minute walk to the nearest subway station, which was perfect for us to get closer to the city center, vatican or Coliseum
Room and bathroom felt and were clean, including the shared kitchen.
Aria even changed our towels after two days which was great.
The only thing I'd mention is that there is quite an echo, so if other guests are entering or leaving at night or early morning it makes a bit of noise outside the room .
The breakfast area was stocked with small yummy things to start the day right.
We stayed for a couple of days, and were satisfied.
Thank you!
