Well on this one you really get what you pay for. It's a basic place to stay and about same price as a Hostel and in essence it's what it is. I have to say that I stay in a Turkish hostel in Portugal that was 19 euros and the place was by far way cleaner. I also understand that paying what Alberto charges, may imply that the place has flaws. However, I think that the price should never compromise the cleanness of a place. It's what ultimately a traveler is looking for. A basic clean Shower and a Clean room. That's it.
In our case, the shower sliding doors had mold on them and the room smelled like feet. The towels smelled bad and the extra pillows in the closet stunk. There were some other guest at the place that it gives the impression that Alberto's place is a Hostel. I mean, nothing wrong with that as long as you disclose it in the air B&B description right?.! If I was looking for a Hostel, I might as well just get one trough Expedia but we wanted a room from Air B&B.
In the other hand he was very accommodating with our arrival time and he provided maps for us. Nevertheless, the things that we expect the most from a place were absent.
