Depending on what your expectations are..
If you look for something "efficient" and unpersonal, a place very well located with a standard sample of equipment and minimum of contact, this is a place you will find ok.
If you look -through your airbnb experiences - for a way to discover one country and cultural habits from the inside, put yourself in a "local" way of living (features, decoration, information about the city) and get a nice and welcoming contact with people hosting you... this is not your place at all !
I am in the second case, and I have to say I felt a bit cheated when I discovered there would be no Paco and Nura to host us, but an anonymous and "far" from client business, with a "team", probably many apartments managed as it would be renting bungalows in a coping area. No family behind the names, no contact, and nobody to host. Even nobody to make sure the place is nice and clean, nor to bring any welcoming gesture.
All the positive and negative I had read about this apartment before arriving revealed to be true.
The location is amazing and the perfect spot to enjoy Valencia : walking area streets, monuments, transports... everything is so close. The apartment is a good size and functional, no major equipment is missing, bedding are OK, and the contact with the "team" ("Laura") on the phone was professional.
But the place is not well maintained, renewed and cleaned at all. The staircase is very small with needs of repair, there is a persistant smell of sewer in the bathroom, the door of the bathroom can't open easily and there is mould in corners, and the cleaning had not been done properly at all... we never felt neither home, nor welcomed.
I am really sorry to say it has been our first bad experience with airbnb.
