About Our Facility A stone’s throw north of Salmon Bay, on the northwest side of Seattle, you’ll find our Ballard storage facility at 2811 Northwest Market Street. Sitting beside the Portage Bay Cafe, just next to the brand new Nordic Heritage Museum and across from The Sloop Tavern. At Simply Self Storage, worries about security are a thing of the past. Our facility is fully fenced, and we have a network of security cameras monitoring the grounds 24/7. Of course, we also provide bright lighting around the facility to help you feel secure here after dark.
