Found this place randomly while looking for central located Airbnb and extremely happy we booked this. Clean, spacious hotel-room-feeling with a very comfortable queen bed. Only negative part were the stairs; 4 flights, bit steep, but worth it. Just think of it as a work out for the day.
Location was literally perfect. Walkable from Vatican, Spanish Steps, and Roman Forum area - a short €10 cab to main train terminal too.
Would definitely repeat and encourage you to stay here. It's part of the next door boutique hotel, Mama's Home, which also looks great.
