Maximalist to minimalist

Sometimes itテ「竄ャ邃「s very surprising when you realize how many worldly possessions you accumulate overtime. The time came for me to face reality and face the facts. Why do I have 84 pairs of shoes and only 2 feet? Why do I have 25 messenger bags but only one body to hang them from? Then it became clear I had a problem, a serious problem. I just need more space I scheduled appointments at more than one location for public storage and this one was the only one that actually followed up on my appointment and gave me may I follow a phone call and ask what time I would be there because he the manager wanted to be there to greet me. Already Iテ「竄ャ邃「m being treated like a VIP I loved it. I showed up early and who is there behind the counter waiting with a smile? Yes, you guessed it, the manager man. Engagement conversation he actually asked what I was storing and I told him and then he explained to me that the unit that I had actually selected was on the third floor, and unfortunately, the elevator was broken and he didnテ「竄ャ邃「t want to see me, hauling all of my worldly possessions up all these flights of stairs ( frankly neither did I) . He promptly swapped out the storage unit and got me another one in and climate controlled building because of the items that I was storing so already heテ「竄ャ邃「s taking interest and ownership of my product and actually caring about my stuff and thatテ「竄ャ邃「s a great feeling that someone else is gonna care about my stuff maybe possibly a little bit more than I do テ「竄ャツヲif thatテ「竄ャ邃「s even possible. Moving was a breeze. The app makes getting to the gate and leaving so easy. You donテ「竄ャ邃「t have to punching codes. I can just hit the little button on my phone. The gate flies open. Itテ「竄ャ邃「s like magic. Overall, this has been a really positive experience. I have nothing bad to say about moving in or obtaining the storage space at all.

My previous storage unit was about to be dramatically overpriced starting next month. I found Public Storage discount offer and immediately took advantage. More space for less price. Also a comment on the office gal, Tabitha. She is professional, friendly, and totally helpful.

We had a million things all going on at once... went to the front desk after check in and the 2 associates went above and beyond to help me out. Very cool people... talked me down off the ledge.

The two gentlemen who work at this location are amazing. Always very friendly and ready to help. The amount of my monthly rent drastically increased over the years. Both of these gentlemen always offered solutions to try to assist me. Because of their diligence an willingness to help this long time customer, my monthly rent cost has been significantly reduced. I am very grateful to them. They are awesome. Excellent customer service!!!

I had an excellent experience at this Public Storage location, thanks to Tsegab and Carlton. From the very first day I opened my storage unit, they have always been helpful, professional, and kind. Today, when I arrived and there was ice in front of my unit, they immediately stepped in to help me without hesitation. Their customer service is truly outstanding. They go above and beyond to make sure everything runs smoothly and that customers feel supported. I am so glad I chose this location for my storage needs. Highly recommend!

Amazing customer service, Let ME know my unit was not properly locked. Heled me transition to a smaller space very easily. Carlton was efficient as well as patient with the storage changes/needs.

Wonderful establishment! Very thorough with explaining the process and very patient. I had issues with creating and logging into the app. The representative helped me upload the app and fixed my issue. I am renting a parking space and plan to return for a storage unit.
