@liuzhou, how long is your lease on this flat/apartment? Are you restricted from doing any changes to the kitchen or can you do things like add extra storage hooks and small racks to the walls, for example?
Your fridge looks interesting to me. I'm not sure if there are 3 separate storage areas and 3 doors? If so, is it two freezer and one fridge or something else?
Also, that looks like fabulous storage to the left of the fridge. How will you use it? Will that be for kitchen items or is that for clothing or just flexible space with shelving, etc?
Edited to add: One of the most important questions to me about any kitchen is where to store spices, ha. How do you (or how will you) store yours?
