Altstadt Bonn looking for exchange in Cologne Innenstadt

Cozy apartment in the cherry blossom street of Bonn Altstadt. It is on the second floor of three in a historical building with high ceilings and numerous windows, which make the apartment very bright. There is one bedroom, a large living room, a separate kitchen and a spacious bathroom with a bathtub. Ideal for singles or couples. I am looking for something similar in the Innestadt area of Cologne, preferably in the south or west of the city.
