This was by far our most awful experience with an Airbnb home. Raul's apartment was so dirty and filthy to make us want to leave straight away. A disgusting mix of hair (including pubes!), filth, dust, and muck covered every single surface of the apartment, from bath to kitchen, to floor and furniture in all the rooms. Hair was even on the kitchen knobs! A persistent smell of urine was in the bathroom, and one of seasoned garbage in the kitchen.
Raul did not apologise, did not recognise the problem, and was not helpful at all. His argument was that that is an old apartment, the apartment where he lives (!), and he had spent the day before cleaning (!). I would love to be able to include in this review the photographic evidence of what we found - such evidence was provided to Airbnb, which recognised the problem, refunded the cleaning charges and about half the price of the rent.
