Holiday property in Spain / Portugal?

Morning all
Due to a bit of a cock up on our part, me and Mr. H are urgently looking for a holiday rental in Spain / Portugal for the 08 - 16/18 August. I just thought I would ask on the off chance that someone has a friend of a friend with such a place who perhaps doesn’t normally rent it out but might be glad of some cash from some extremely well behaved tenants!
Any leads very gratefully received!
