Hi there! I am travelling to Bonn for an Erasmus BIP program (one week) and I was going with a friend but he told me recently he can't come. I already have a reservation in a hostel for the days mentioned, you would not have to pay anything for the accomodation.

We can visit Bonn and Köhln, we could even go to other beautiful places that are in the area. I speak German. 

Feel free to contact me if you're interested.
