After the '93 flood my family had to seek temporary shelter in an apartment complex where obviously all of our personal belongings were not going to fit. My parents rented out a storage unit until we moved into our house. They have some climate control ones that are very nice. I was too young to remember a price (even then, it was so long ago prices are bound to have changed from inflation) but I do remember it was relatively safe and nothin did happen to them. Though I'm sure it's about location. Just make sure to choose a facility that has a good reputation and perhaps choose an indoor unit
