There are several storage rooms in Juustenintie 3 apartments. Please remember that there is no specific storage facility reserved for any apartment.
So, in order to book a storage facility for yourself, find an empty locker in any storage room your keys can open and buy a lock for it. Whenever you see a free storage space (without locks/ or any items), you can reserve it for yourself.
When you move out, remember to clean and leave it open. Please do not occupy more than one storage space.
