“A very good experience! I showed up, and was given a tour on the spot. The paperwork was a little complicated but Jessica the new manager here was very proficcient and cut through the red tape for me. I have the option to pay monthly by phone, online, by check or by mail. Clean facility, very secure, and I have the option to make my access code whatever I want! I had a unit at a Public Storage facility prior to this and this experience is so much better! So much more flexible. I’m impressed!”

Yelp Review - Greenwood Heated Storage

“I had a great experience with the staff and their willingness to help me.  Judy is an exceptional manager and will do what ever it takes to accommodate your needs.  It’s not very often you receive customer service like they provide.  The location is clean, well maintained and has a great surveillance system.  I highly recommend them.”

Yelp Review - Eagle Self Storage

“I went in to look at units and rent a truck. Tessie was wonderful, funny, and knowledgeable. Although my need for a unit changed, I still rented a truck. When my need for the truck ran longer than expected, Tessie helped me extend my reservation smoothly. She took a load of stress off my shoulders during a difficult time, and I would absolutely recommend Tessie and her facility to anyone looking to store or rent a truck.”

Yelp Review - Affordable Self Storage in Bothell

“Great first experience, we’ll see how things progress, but the ladies helping me were great. Well organized, knowledgeable, and genuinely friendly. I came in right after I got off work, but 15 minutes before their closing time. No problem to them. They got me all setup, explained everything really well, got my free truck rental scheduled, and even gave me a tour, all within about 25 minutes. Hope things go as well as they started, and I’m sure it will!”

Yelp Review - Everett Storage Depot

“Stacie and Spike were great! I walked in needing help finding a storage unit for a last minute move and Spike immediately came to my rescue with a tour and demonstrated how to properly use the lock since I had no idea what I was doing. They gave me such peace knowing my stuff would be kept safe and their prices are amazing! Stacy helped me gather all the movie supplies I would need to help my move run smoothly. I would highly recommend 145th Storage to everyone!!”
