Roommate in Madrid center?

Hi! My name is Jonathan. I am 32 years old and looking for someone to share a decent two-bedroom apartment with somewhere in the center of Madrid. 

Originally from New York City, I'm a single university lecturer living in Madrid for five years now. Ideally I would be looking for a very clean, organized, responsible roommate who is also friendly, fun and open-minded. Around my age would be ideal. No smoking / No drugs please. Anyone else looking for a similar flat mate? Write me on WhatsApp if you would like. My number is included.
