Flamenco Dance & 2 months accomodation ?

Im going to Madid within 3 weeks to advance a little more with my Flamenco technique, Im looking to stay about 1-2 months and would prefer a share apartment to a hostel- cheap, central to the main parks & activities and safe. Im wandering if any one would know of a senora I could stay with or if there is any short term boarding available anywhere ?
Any help would be much appreciated
Thanks Belly
