This place increases the cost every 3 months it is crazy. Just received a letter and they are increasing the rates 40 percent. The staff is the best though.

I am extremely happy with the front desk receptionist, Chelsea at the Middleton storage. She was extremely patient and understanding when I had things going on. Her customer service skills are 10/10 in my opinion. She is extremely sweet and she was super helpful with my dad as well. Would definitely recommend them for a storage place.

Chelsea always went above and beyond, no matter the situation. She was ALWAYS cheerful, helpful and cordial. I had several constraints at the time I rented a unit there. Chelsea always managed to mitigate any potential stress I was having from a financial/payment standpoint and worked diligently with me to provide options and support. I rarely come across the level of customer service that Chelsea provides anymore and when I did experience quality service in the past, it would rarely repeat 24/7 quite like the way she has always provided. Thank you
Chelsea!!
