A very nice appartament. Big, clean, warm, situated in an old and elegant building. It is 20 minutes walk from the Vatican.
So is a little far from the centre. But you can take the metro (7 minute walk) and you arrive quickly in the Piazza di Spagna.
The problem is in the ievenung, the last train is at 21.00 pm. Anyway, the cab is not expensive.
Nicolo is a very nice host. The communication was very good with him. He also let us to storage our luggages in our last day when our flight was very late.
