22 year old girl looking to rent a nice apartment in Madrid

Hey! I'm moving to Madrid to start work as a consultant and I'd love to find someone to rent an apartment with. I want somewhere nice, my budget is about 600 each (we could get a really nice two bedroom for 1.2k or even less). It Would be great to find someone who is easy going, I have a lot of friends in Madrid who might want to come and say hi or pop in for dinner. I need an outgoing person, easy to live with :) I'm not strict on rules either I don't smoke but I don't care if you do. I don't mind if you have a pet either.
