We are talking about a 15qm2 room right in the middle of cologne. You can even see the Dom. That means you have direct connection to all the places you want to go to. It is also very nearby the central station.
The apartment was like we expect and looked the same like the pictures. It has everything you need. The location was good and everything was within walking distance. We didn't meet Jannik, but the communication was very good, also during our stay. His roommate let us in and showed us around. I would recommend Jannik's place for a weekend Cologne!
Jannik's appartment was nice. It's a student WG but comfortable. He had cookies for us when we got there. The only thing was that I had the impression that the heating didn't work, but when I told him he said it was strange and would check it out. He seemed like a really nice and friendly guy.
Jannik's flat is located in a very interesting part of Cologne. Just 2 minutes walk from the underground and 10 minutes by foot to the central station and cathedral, this apt is well situated among eclectic cafes & restaurants, mom & pop shops and vintage records stores. Though I didn't have an opportunity to meet Jannik in person, he was attentive and helpful via email. His girlfriend met us and let us into the apartment and showed us where everything was. We stayed in Jannick's room for the trip and shared the flat with 2 of his (SENSITIVE CONTENTS HIDDEN). In general the flat has a college dorm vibe and would be good for those only needing a place to sleep, as it is missing some standard features of most Airbnb rentals. A dresser drawer to store clothing would have been nice (we kept our clothes in the suitcase on the floor). We were offered use of the refrigerator but when we came back with food there was no space. Ultimately we had to keep food cold on the window sill in our bedroom. Another issue we had was with the toilet, which is flushed by pushing down on a kitchen fork sticking out of the top of the tank. Sometimes this worked. At other times we had to lift the tank lid and re-position it. In one case we resorted to flushing the toilet with a pot of water from the kitchen. Hopefully Jannick could make a few changes that would make the space more hospitable to visitors. He's a really nice guy, with a terrific location and lots of potential as a nice destination. Best wishes Jannick on your apartment and thank you for hosting us.
