hmm find it not possible to edit my own post.
Just wanted to inform I'm not looking anymore for apt. next summer as I found one.
I found
Caballero de Gracia Apartments in the
Apartment section of this board that I feel is a good buy (€50.00 a night) extreme well located in the middle of everything and just around the corner for don Quijote
later: oh well found how to edit post but not to delete
