Dario is a very nice host and gives you lots of useful information.
The room and especially the bed was very comfortable.
We had a bad weekend in regards of public transportation in Rome as parts were on strike - nothing what is in connection with the accommodation. But with that the distance to the center becomes more relevant (aprox. 20mins walking to Colosseum, 40mins to the center).
The breakfast is very good and underlines the great hospitality of Dario!
One more comment: the room is located in a nice older building with simple windows and doors - and Rome can always be a loud and living city
