American, 26, working, looking to rent room in Madrid

Hello! My name is Josh.  I am from the U.S., although have worked in Madrid for a few years now (Marketing).  I am changing apartments and am looking for a room to rent, preferably with roommates around my age, educated, working, sociable, and like to have a good time together (grab a drink, hangout, etc.).  Budget is around 400-450. I speak English and Spanish!  Feel free to send me a WhatsApp including a little bit about yourself too.
