Does anyone know of a bed and breakfast or other alternative lodging to recommend in Cologne?
Have you looked on Trip Advisor, or www.hrs.com yet? I often just google B&B or pension for whatever city I am going to.
That said, I often recommend the Coellner Hof hotel in Köln, simply because it is lovely, and affordable and offers about the best breakfast buffet I have ever had.
