Chas, at least you know Kiel is on the Kiel Canal (locally called the Nord-Ostsee-Kanal, or North Sea-Baltic-Canal)= water. It's also on the Baltic via Kiel Firth = more water. It has an attractive venue (though not exclusively folk) in Hof Akkerboom. And, most important of all: It has me as a citizen. What else do you need to know? :-))

If there is anything else you could try asking, or try the link I gave above: Kiel

General question: Would anyone like a guided tour of the city?
