Very disappointing. Announcement is not transparent as it does not show its entrance in poor conditions as an unfinished construction worksite with dust, bricklayer and unfinished conditions, not to mention the unfinished and hazardous stairs.
In addition, apartment had an awful smell, apparently of cigarette. Such smell was across the whole studio, making impossible to stay inside.
Unfortunately I had to call AirBnB Resolution Center to support me with cancelling such reservation, and the company which looks after this place at least accepted to cancel the reservation and grant a full refund.
Quite sad experience that disrupted my arrival in Valencia and forced me to cancel an appointment.
