We used this facility as part of a UBox move. Everything went smoothly and we appreciate all the communication from Moving Help on delivery day. This is a great way to move a small amount of items.

I would like to say that Santos and Jerome at the Rainier location went above and beyond to help me with access to my storage unit. They both deserve recognition for their great customer service!

This facility could not locate my ubox for 2 hrs even though uhaul confirmed they were supposed to have it. I called to speak with the manager about it but they never called me back. Distressing.

Billielee B. on


The staff here is fantastic. From the manager to the person who mops the floor, everyone is helpful and very accommodating. I would totally recommend them.



Every step of our U-Haul box was on time and as expected. Thank you.

Sachin A. on


They need to update their help desk. I called the location and the person on the phone told me the UBox hours were 9-8pm. I went there at 6:30. They told me the hours were 9-4. Extremely frustrating.
