- JPJoe PlesciaFeb 4, 20265.0Jenny has been fantastic to work with during the construction and remodeling process. Great communication and cooperation from her and her team. Have a lot of respect of how her and her team treat and speak to customers. Highly recommend this facility for your storage needs.
- DVDayne VenturaFeb 3, 20265.0Knowledgeable and professional
- GBGregg BauridlJan 22, 20261.0Raised my rent after the 2nd month by 30 dollars and 3 months later doubled it to 150 a month for a little 3x15 space. Ridiculous. I do not recommend unless you enjoy getting screwed over. I understand an increase because of market changes but to double from 75 to 150 is absurd. The only good thing I can say is 24 hour access was convenient for a person who works nights but doesn't outweigh the constant price increases
- AWAlexandra WinzenJan 17, 20261.0I started renting a unit last fall and recently received a notice that my unit is now double the cost starting next month due to the market. I understand increases over time but being with this company less than 6 months and having my rate double is ridiculous. Extremely disappointed that I made the decision to go with Extra Space.
- ANAmmiel Von NidaJan 8, 20265.0I had an indoor, second floor unit at Extra Space Storage on Mexico Road in St. Charles for almost two years and overall had a great experience. The facility was always clean, carts were consistently available for moving heavy items, and it was never crowded. There is a door right by the elevator that you can pull up to, which made loading and unloading into my vehicle very easy. Every time I interacted with the office staff they were pleasant and helpful. Jenny Pinkston truly stood out. She was kind, professional, and went above and beyond to make the move out process smooth and stress free. Her customer service made a lasting impression and really reflects well on this location. All of my belongings came out exactly as they went in, clean with no mold, bugs, or dirt/dust. I had zero issues the entire time I was there and would absolutely recommend this location to anyone looking for a reliable, clean, and well managed storage facility.
