Update (for anyone interested): I received my luggage after 23 days (so basically too late), but everything was inside and fine.
I still sent them my receipts for the taxi ride to the airport (had to pick up the bag), some cosmetic stuff and medicine (eye drops).
They paid for everything except the eye drops cause it is considered medicine. The total amount was only around 70 Euros for everything (including around 10 for eyedrops).
Basically I'm happy, cause I got my stuff back and got reimbursed.
