I didn't meet Dario, but his father was kindly there to greet me approximately 2-3 hours after I said I'd be there (got stuck in a rainstorm).
Dario's father doesn't speak English but the communication doesn't seem to be a problem. The room and the bathroom were extremely clean and modern.
Something I wish I had known: this place is in a bad neighborhood. There were prostitutes on corners and groups of people congregating/ loitering on sidewalks at all hours of the night and day. I only felt really safe when a military police man actually offered to escort me home around 10pm on a Sunday. I just would recommend that if you are a woman coming by yourself then you should maybe look for a different area to stay in.
It is not easy to get to Venice island or back to Dario's place (especially with luggage).
Otherwise, Dario's father was wonderful and the room is definitely like it is in the pictures. I recommend this place if you just need a place to stay closer to the airport than Venice island!
