I arrived very (very, very) late but Dario was very accommodating. The room was quite large and clean. The (private) bathroom was down the hall but spacious enough (and the B&B part is separated from the rest of the apartment, so not really a problem). The apartment is located not too far from two metro stations (San Giovanni and Re di Roma) and it looks like the future metro line C will have a stop almost right in front of the building. Both cats are very discrete (and so is Dario).
