From the south, e.g. Hamburg, Neumünster, drive to the end of the A215 motorway (towards Kiel).
About 250 m before you reach the end of the motorway for Kiel-Zentrum, take the exit onto the B76 (by-pass) in the direction of Lübeck (East). Follow the B76 in the same direction for approximately 9 km.
Take the exit towards Schwentinental (at the end of the large shopping area on the right). At the traffic lights, turn left into the Preetzer Chaussee and across the first roundabout. Continue for approx 250m and bbe Moldaenke is on the right.
Directly from the arrival terminal the airport bus "Kielius" goes to Kiel main station / central bus station. From there you can take the public buses (300 direction Raisdorf, 4330 direction Plön, stop: Oppendorfer Mühle) to bbe Moldaenke. Of course, taxis are also available in front of the main station.
Price at the time (Sept. 2018): One way ticket: 21,00 €, Return ticket: 37,00 €
A bit more expensive, but more comfortable you can go by "Kiel-Exx", a minibus shuttle, which also leaves directly at the arrivals terminal. This goes without stopover to Kiel, where a taxi is already waiting for your further journey. (Reservation needed!)
