Is 1500 euros enough for a couple to live on in Madrid?

Hello, I have received a job offer from a firm based in Madrid and I would appreciate some help concerning the salary. They are offering me 1500 net for a project coordinator position. I am not married, but I am living with my partner (have been for 8 years now), so of course he would be moving there with me. Since he doesn't speak the language, I would have to provide for both of us until he picks up some Spanish and manages to find a job - which could be a few months up to a year. I am very interested in the position, but I am making not much less than what they are offering as a freelancer, and, from what I have seen online, Madrid is an expensive city to live in, at least as far as rents are concerned. Could someone give me some insight? Are rents truly as insane as they are said (and seem) to be? Would we be able to live there (perhaps not comfortably, but at least properly) for a year on that amount of money?
