We stayed as a family of 4 and there was enough space in the flat for us.
2 double beds in 2 bedrooms, kitchen and a large bathroom.
it is located on the 4th floor but there is a lift.
location is fantastic. 5min walk to fountain de Trevi, 25 min walk to Colloseum,45 min walk to Vatican. perfect location if you want to see the Rome and walk around.
thanks Andrea
