Disappointing, would not book again.
First off, this is not really an airbnb and property. "Nuria & Paco" may be the owners but the property appears to be run by an agency. So the fact that it belongs to "Nuria & Paco" is fairly irrelevant, as the experience is impersonal.
Second, the woman from the agency showed up over 20 minutes late to let me in. This would have been bad enough in any situation, but it made me late to meet my mother at the airport.
Third, when we entered the flat it was clear that the floors had not been cleaned/swept. When I pointed this out, the agent showed me where the mop and brush were... so I guess she expected me to clean it up myself. The issue was resolved when I contacted the agency by phone and they sent someone around to clean up.
Fourth, we were two separate guests so I asked for bedding for the second bed. Bedding was supplied but it was not warm enough - and there were no extra blankets or duvets in the flat.
Finally, the kitchen area was dark (broken lighbulb/s) and the bath/shower was dirty: the plug filled with somebody's hairs... very unpleasant.
The front door to the building was too heavy/stiff for my Mother to operate. The stairs were extremely narrow but that kind of had character.
On the positive side, the price, location, flat itself, heating/air conditioning, were all fine.
Still, I wouldn't book it again or recommend it.
