After having secured a VERY late check out from the hotel, we went to see the Chopin museum which was nice.
We then searched for a specific shopping mall, which was not what we expected, so we returned to the hotel for some lounging, resting and eating. :)
We then checked out, took a train to the airport, did some tax-refunds (in a horribly bureaucratic Polish manner) and headed home on a red-eye flight.
