The Flat is a Loft in the Südstadt, wich is a silent area in the heart of cologne. In just 10 minutes you're at the main Entrance from the Messe Deutz. You have to walk 5 minutes to the S-Bahn and after just 2 stations you're at the messe.
4 minutes by feed you're at the Rhine next to the Kranhäuser where you can have nice dinner or just have a nice walk to the Cathedral.
During the Big messe dates my Roommates and me are renting our rooms, so maybe you gonna stay here with other visitors.
