Our little city "Loft" (ground floor!) is located down town Cologne. It is a perfect place for working, sleeping, meeting.
It has 1 double bed and a sofa - so you can stay with three (up to 5) people or a family.
You find restaurants (african next door / thai opposite - both great), cafes (Café Central - fantastic), the arthouse cinema "Off-Broadway", the "Aachener Weiher" (chilling) and a wonderful 8km (more ist no problem) jogging lap through the park.
