Hi!
First day for me in this forum, I'm from Spain but I'm living in UK, Miguel Angel Escultor is a very good choice, and there is another one in the same street with excellent suits and it's cheaper I can't remember the name, but it shuld not be difficult to find it it's 300m down the street. If your aopa discounts are not accepted try with this, go to a travel agency and ask for "cheques de bancohotel" for 7.500pta (that's 3.750 per person not too bad!)you will have a double room in the best hotels of Spain, in Madrid is especially convinient for weekends.
Hope this helps!
