We needed to ship a car to Seattle so we could drive it back to Alaska. Kadie from SeaTac Self storage was very helpful and allowed the car to be dropped off and held until we could fly down to get it. When we got inside the battery had died and she went out of her way to help us jump the battery, first with a machine and then her car. She absolutely saved the day and we recommend this place very highly!
