I have to say I am loving my life in Königswinter. I moved here 2 and a half months ago and it's been nice. I am very close to the river. People are saying Königswinter is far away from Bonn, but it's only 14 minutes by car. Haven't tried public transportation or biking (using prosthetic legs so biking isn't an option :D) but it seems close enough and 66 line is quite frequent as well. Also, there is a ferry every 8 minutes so you can avoid the bridges and be in Bad Godesberg in just a few minutes.

The city is nice and calm, except on the weekends when it's full of tourists. I already have a favorite cafe with pretty good ice-cream and am enjoying my walks along the river. That being said, if I were a normal 28 year old I'd probably be a bit bored because I don't see a lot of young people or clubs here. But in these COVID times I don't yet care.
