Couple from USA seeks dog friendly flat

I am an IT consulting professional, my girlfriend works in film and television. We are non smokers, and enjoy a healthy amount of socializing. In my free time, I enjoy writing music, singing, hiking, and learning. Our dog is very friendly, and is certified in the US as a Canine Good Citizen by the American Kennel Club. He is a large mix breed dog, but very calm and non disruptive.

I am starting a job in Köln at the beginning of October, so we are looking to move in September or the first week of October. We would prefer something with furniture included, but only require a built in kitchen. Phone number listed is a US number, with +1 extension. Please email, text, or call with any questions you may have!
