I can highly recommend to B&B for several reasons:

Marco is a great host and very helpful (recommending a restaurant, booking a taxi etc).
The room is very clean and comfortable with a very good bed (I travel frequently for work so been in several hotels).
Very clean bathroom with everything you would need.

The B&B is very close to the Metro 7 minutes walk or you can take the 916 bus into the center or to the metro.

Our next visit will definitely be at Marco again and will recommend it to family and friends.

Grazie Marco
