My flight to Lübeck was so early that my best option was to sleep at Stansted. My plan was that this would be a little bit less tiring than getting up at 3am, but then I met a fun bunch of people on the last train to Stansted, we played cards all night on the airport floor, and I was destroyed by the time I got to Germany.
I stayed in a hostel in St. Pauli, overlooking the docks. It was grey and cold, and an icy wind was blowing off the Elbe as I looked over the huge expanse of cranes. The bracing conditions at least woke me up a bit.
