Manzoni's apartment is well located near to the Termini station, to the underground and to the Colosseum as well. Paolo and his assistant are very nice and helpful.
The flat is nice and quite small, ideal for 1 or 2 person, but we were very disappointed when we realized that the apartment is actually a suteren and quite cold in the winter season despite the AC. Unfortunately the bed linen was not perfectly clean neither.
So we were not satisfied with our choice and in my opinion is not a value for money.
