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

These amenities include Climate-Controlled, Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Enclosed, Elevators, Multi-Level Storage, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Extra Space Storage - 3939 Mexico Road can satisfy all of your storage needs. Different sizes here range from 25 to 400 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Extra Space Storage - 3939 Mexico Road come at a variety of prices, starting from $41 per month for typically smaller units. However, larger spaces can set you back up to $697 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
