Allison Swatt

Place is very clean and staff is friendly. Security is a priority here - cameras around the property and staff on property 24hrs. Prices are reasonable.

Michelle Guykema

Sherri is amazing! Her professionalism, energy, smiling face and friendliness is much appreciated during a stressful time. Thank you Sherri for making my experience a pleasant one.

First storage unit I've ever rented at, they seem to have it together. It's a room, with a door, that I can lock. It was empty when I got there. The driveway is gravel though which makes moving the heavier things like safes, dressers, and toolboxes kind of difficult. It works. Not sure else what to say.

Alex PNW

The office lady is super sweet! Great storage. Nice vibe

Thomas Shaull

Lost my key to the unit and John was instantly a help to me gaining access before I had to go to work. Also. I have had other storage units with public storage and have always had issues with mice , but not this place ! Always clean and of course John being on site always provides excellent personal service. Great Job, John!

Brandon Wigington

John has been an outstanding host and I sincerely can't say enough good things about the way he handles his property and the people who utilize it. Without John being as patient as he has been with several people through this whole Cova-thing, a lot of people would be far worse off than they are currently. Thank you for everything John!

Super friendly! Very cleanly and the customer service couldn’t be better! Jim was so helpful in every way making the process easy and even helping with disposal of unneeded items and suggestions on movers and how to donate to charity. I am so glad I chose this location!

Nick Brugato

This is a very secure facility that I trust for my storage needs and when I lost my lock key the gentleman was really nice and removed the old lock for me!

Sammie Graham

Signed up today. It looks like a very nice place. The owner John made it a very enjoyable experience.

Ken Mesa

Easy to find while driving. Close access to I-5. Property is clean and Jim was very open to any questions I had. Love the fact that it has HD cameras all over the property. Crystal clear picture on the cameras. Definitely would recommend others to this place for storage needs. Pricing was by far better than others storage places I’ve found and the accessibility to the unit was a plus.

Lavern Peterson

Great friendly customer service. Helped me find the right storage unit to suit my needs. I recommend this company and location if you live on the South Hill.

Jim is very nice willing to help you with anything that you need and work on getting your rent payed so you don't lose your unit. If I ever move back to Washington state and need to rent again i will go back and see him.

Excellent! Extremely safe! Management is very helpful.

Nathan Lucas

I was referred here by a friend/coworker and just started with them today. The process of getting a spot for our travel trailer was seamless. John walked me around the property and gave me all the details. The facility is clean and secure with a good amount of room for bigger vehicles. Management was helpful and really friendly, which goes a long way. If you're looking for storage near this area, stop looking and book here. Highly recommended.

While I never actually used Cobalt for storage, Sherri did everything in her power to figure how to get a UPack ReloCube for my upcoming move. She was the only person in the area willing to let me have a ReloCube delivered and stored since the parking at my apartment isn't conducive to having one. I cannot thank her enough for her time, energy, and creativity in helping to make that a possibility.

matt ireland

Awesome customer service! Owner came in on day off to get us set up! Would recommend to anyone!

We have rented multiple times at Cobalt Storage in Milton, Jim has been so very nice & helpful with each of our rentals. We enjoy the fact that we can get to the storage quickly & they have great hours to access our stuff:)
