Quite average Hotel but pretty typical for italian conditions. Old furnitures, some dirt here and there, bathroom gets flooded while taking a shower, bad painted walls and so on... The typical italian way of life :-)
The bed is quite hard.
On the other hand not too expensive, good service (new towels each day, bed is done every day), nice crew.
The rooms are in floor 4, the reception is in floor 1, outside it was written floor 7, a bit confusing to find.
The city center is not that close but metro station and busses around. Walking distance to Vatican around 25 min. To Collosseo around 1 hour (25 to 30 min by metro). To Spanish steps around 30 min (10 min by metro).
Overall a good stay for 3 to 4 days if you don't expect too much.
