Great location. Very clean. Competitive pricing. Friendly staff.We have used them twice in the past 7 years to store our property as we moved homes. Each time they were helpful in selecting the right size, the right location within their units, and answering any questions we had. The property is very clean both outside and inside their units. We utilized their carts to move items in and out of the buildings. They were well-maintained and always available. We highly recommend Guardian for any of your storage needs!

This place is awesome! Month-to-month rentals and the staff is so friendly. Plus there is a free truck rental with move in which makes it that much easier to get your stuff there without an added expense. My mom rented here for a long time as well and we've both had nothing but pleasant experiences with everyone who works here. 100% would recommend them to anyone looking for storage in this area!

Wonderful experience with renting and storing our belongings. The staff was friendly and helpful with all our moving needs. They also have a rental truck that you can reserve to help move your belongings into storage. Highly recommend Guardian Storage.
