First of all I'd be happy to welcome you in my lovely apartment in the Centre of Cologne. It's located between rudolf and friesenplatz and around the corner of my favorite neighborhood Belgischen Viertel. Here you can find tons of cool bars and cute little shops. I have a big terrace, separate kitchen and bathroom and a studio with my bed in it. I'm sure you can enjoy Cologne to the fullest, living in my place and being more than central!
