I rent a a cozy apartment for tourist here. The room has a bed, which is big enough for 2 persons, a table, and a frame. One can use the bath, the kitchen, and my wireless Internet (Wi-Fi).
The apartment is located in a very good convenient place of Cologne, one can only need 1 minute to the subway station, 1 minute to the "Ringe", where you can make good party. Into the historic center and to the fair you only need a few minutes with the subway.
I would like to say that the apartment is in the fifth level and there is no elevator, but I will be more than happy to help you carry your luggage.
Do not hesitate to contact me, if you have any further questions.
See you - Freddy
