I just moved in last week. I will be moving out. I stopped by around 930 to move some stuff around - within 30 minutes there was a knock on my door extremely rude woman said I’m not allowed to have my door closed and then she claimed I’ve been there since 7 AM. What? I was on the other side of town at 7 AM. I was puzzled Why do I even rent a storage unit if I can’t even be inside of it? She said I needed to leave shortly and I have to keep my storage door open at all times? So I will be moving out at the end of the month. I will not do business with a place like this. The lady was so rude the worst customer service experience ever. Also don’t let the website fool you - see videos - it’s not as nice as it seems.

I had an excellent experience from start to finish while securing my storage unit. The staff was professional, knowledgeable, and made the entire process smooth and stress-free. They took the time to explain my options clearly and ensured I was set up with exactly what I needed. Outstanding customer service—I highly recommend them.

Ted and Sean were absolutely amazing. They made a stressful situation like change and moving pleasurable, easy, and stress free. Great customer service skills, thanks guys. I’m now looking forward to the time utilizing my storage unit. These guys deserve a raise!

Sean and Teddy were the bomb. Customer service was above and beyond they made the whole experience extremely pleasant and enjoyable. They even laughed at my stupid jokes. Thanks again Teddy and Sean if I ever need storage again, I will be back.! And if you need storage, you should definitely go to them!!
