Thank you for adjusting with me when I upgraded to a 10 by 20 from a 5 by 10 on move in day! I really appreciated how easy and fast it was to adjust on the spot! ?

During my tour of the facility, it looked clean and well maintained, with a simple layout and adequate space to drive through. Christine is knowledgeable and efficient with great customer service skills, I had several questions and she was patient and helpful. They have many accommodations to make a move fast and affordable such as packing materials, boxes, protective covers and moving trucks. I will be moving my belongings in this weekend.

I have only just joined but the young lady in the office was very friendly and accommodating. A pleasure doing business with her truly. I don't foresee any problems in the future. I am grateful to have found them.

Best experience leasing a storage unit I've ever had! Hands down. The process was so streamlined and simple. The property manager Christine was over the top helpful and helped me get the unit without having to take time out to go down there in person on time crunch moving day. Seriously, she's A-MAZE-ING!!! If you're torn on where to get a storage unit, this is the place to go!

well I had went in weeks prior to arrange and even paid for reservation for a storage and it was supposed to be half off first month and already 2 weeks intothe month. I walked in there today only for them to delete my whole account we had set up before. nothing was explained and she charged me for full month she seemed like she didn't know how to use the computer. super frustrating. and on the first day. drove half hour to get there she told me she couldn't rent it out to me today.i then told her I had rented a uhaul and then that's when she erased my account and started a new account. seems like businesses not just this one is always trying some scandal

The nice lady running this storage facility is absolutely amazing. I had a unique situation and she did absolutely everything within her power to help me. Oak Harbor has plenty of storage places, but they don't have her. Highly, highly recommend !!
