    Great experience renting a storage unit here. I booked everything online the night before I needed to move in, and by morning I had a text with the gate code. When I arrived, the unit was clean and ready to go (with a lock and key already waiting inside). Couldn’t have been easier. The whole place looks well maintained, and I even got a friendly call from the office just to check in and see if I needed anything. Great facility, kind staff, seamless move-in. 10/10. ... Read more

    The online rental process could not have been easier. Once arriving at the facility, the lady on duty was extremely welcoming and beyond helpful when loaning me a flat cart to transport my belongings. The facility seemed exceptionally clean amd well protected. This is the second time I have rented from Extra SpaceStorage, but my first at this location. Definitely impressed with the property as well as the staff ... Read more
