Self Storage company in Germany

Hello my neighbors. I seek to locate an acceptable self storage company in Germany that I may store some of my belongings for a few weeks. The amount of storage space that I require may only be a storage room of approximately 25 ft by 25 ft. This is not a large storage unit, but it would be adequate for my needs. When you email me with your information, please also include answers to my questions. Does your rental or lease agreement provide for a discounted rate for longer storage terms? Is my property insured against theft or damage caused by fire, flood, or any other event? What are your current rates that you provide your storage services for? Do you have any restrictions of what I may or may not store at your facility? What I need to store are some of my furniture, tools, and some other personal items. I am unsure of a precise period that I will require the use of storage. I only estimate it to be about 5 or 6 weeks or so. Thank you for your prompt response to my inquiry.
