one night accomandation in ´Koln-Bonn

Hi,

I am traveling to Koln in Easter time. I want to spend a day in Koln to visit Kölner Dom. So I will need one night accomandation in Bonn or Köln. Is here anybody can help? I can pay you. please contact with xuyang61@hotmail.com if you have any information. Aslo I think I will use GermanyWing to be my summer European travel ticket company, so I will come and visit Köln next time for going to other countries. If you can provide accomandation in the future, we can make up plan together.

Thanks
