The house is at a pretty good place. Just a couple of minutes walk away from Termini station. Also everything(colosseum,forum,trevi fountain, spanish steps) is at walkable distance from the house. We only had to take the metro for Vatican city.
Wifi is a bit poor and there is no common room for everyone to sit. But the house is very pretty and spacious. The host gave us pretty good local tips and provided us with a map with everything marked on it that we can visit. The building has a lift, so good for people with a lot of luggage.
