Help with bicycle storage in Copenhagen, 3rd to 9th of October 2018

Hej :)
I am not heading south from Scandanavia, perhaps toward the Balkans and into Greece for the winter. I need to fly back to England briefly to send off papers for my Irish citizenship so I bought cheap tickets from Copenhagen on October 3rd and back on the 9th. However, I can’t take my bicycle so I am trying to find a friendly that may be able to look after my bike and gear for the six days I am away (could also be good to have a host either end of that). 
I have a “small” sized Genesis Tour de Fer 20 (700c wheels) and a full set of panniers plus small hydration backpach. If anyone has space for these or can help me find a solution it would REALLY help! My wheels kind of need trueing (which I should learn to do myself) so I was also thinking maybe a local bike shop could sort my wheels and may be able to hold my things, anyone know of a good place? I have very little money so can’t pay for storage. 
I appreciate any ideas :)
