Read some helpful reviews of Extra Space Storage at 3939 Mexico Road, shared by real renters with genuine experiences and honest opinions.

Jenny 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. ... Read more
Joe P. - 4 February 2026
Raised 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 ... Read more
Gregg B. - 23 January 2026
I 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. ... Read more

Ravin P. - 25 July 2025
Big Shout Out to Genny, she saved me from another day of searching and disappointment. All day I tried every storage place for car storage to no avail. I came home and searched the internet for a place lo and behold I found the last one at this EZ Space. Finally, I could take this off my plate so I relaxed when I found a place to store my car. Genny said I could do it right now to ensure I got the spot, of course, I said Please I'd love to take it. So with that done, I could now relax after this stressful day. The price was so reasonable and it's right off the highway which makes it easier for me considering I live in South City and they're in St.Peters. So happy to work with Genny she was so friendly and helpful in getting my mission accomplished after trying the entire day. Great asset to this company for sure! ... Read more

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 25 to 400 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Monthly prices for units offered by Extra Space Storage - 3939 Mexico Road start from $41 and can go up to $697 for larger spaces.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
