I am renting my appartement in a really friendly part of cologne. The appartment is quiet and sunny. There is a lot of space for one person, its even big enough for two. The apartment has one big room with one sleeping and one living part. There is also a small but seperated kitchen and a bathroom with bathtub. If you want to go to the city center, university or the river rhine, you need about 10-15 minutes by metro. The metro station is close to my apartment. You are welcome!
