Rolando G. - 21 February 2026
Extremely disappointing experience. This facility operates with little to no on-site staff presence. On multiple occasions, there was no employee available when assistance was needed. When I did interact with the employee, Alex, the level of professionalism was unacceptable. Alex was consistently distracted on his phone during conversations, appeared disengaged, and responded in a dismissive manner. Basic customer service — eye contact, attentiveness, respect — was completely lacking. It felt like customers were an inconvenience rather than the reason the business exists. If management is going to operate with minimal staffing, the least they can do is ensure the employee present is attentive and professional. Storage is about security and trust. The current customer experience does not reflect that standard. I would strongly encourage ownership to address this before more customers have similar experiences. ... Read more

I went in on a Sunday to drop off some stuff and get some stuff I needed. I had a small problem and Alex came to help us. Not only was he very friendly but he gave us all the information we needed to fix the problem and gave us step by step instructions on what to do next. Its because of staff like him that I am happy to be a customer of this storage facility. ... Read more

Such a great business! I was greeted very professionally and courteously. I was brought on a tour to the unit I reserved, so I got to see what I would be paying for before paying for it. The cost was broken down clearly, including potential increases in the rent since the cost I got was promotional. The security that they have also gives me peace of mind leaving my belongings in my storage unit here. I would recommend this storage to anyone who needs one! ... Read more

Absolutely fantastic experience at Smart Stop Storage! Alex, Elvia Will are absolutely superb. Their customer service is top-notch—super friendly and always willing to go the extra mile to help. Moving is always such a hassle, but they made the whole process so much easier for me. The facility itself is very clean, safe, and affordable. I highly recommend this location to anyone looking for storage. Thanks again, guys, for making everything so easy and stress-free! ... Read more

Elvia was a WONDERFUL help! She wasn’t trying to push the sale and allowed me to make the decision on a space I wanted. She was super funny and personable. The location is clean, well kept, and Elvia is an excellent rep of this brand. Ask her about ELVIS! ... Read more

Excellent service from Alex! I got there later than expected, and he patiently waited and made the rental process very smooth and easy. I also recommend getting a storage unit here if you are looking for something affordable. It was the cheapest in the area of Santa Ana, Anaheim, garden grove, and orange. ... Read more

Edmund F. - 17 February 2025
We’ve been storing our household goods here for a couple years and have never had a single issue. Unfortunately I didn’t have the same pleasant experience at a previous storage complex (mini u storage in Santa Ana) where my unit was broken into multiple times in a matter of months. I have never worried about whether or not my personal items were safe at smart stop because I’m very happy with how security is on top of things, the cylindrical lock they use on the doors is very secure, buildings do not need repair, grounds are clean and well kept, and most of all courteous staff is so pleasant to deal with if you ever need to speak to them about anything. There’s literally not a single negative thing I can say. I’m happy and grateful I chose this smart stop as my storage choice. Big thanks to Alex and Elvia for their outstanding customer service! ...

HNRS O. - 8 January 2025
The time I came here for service Elvia was so helpful, she was patient with all my questions. She went into great detail of pricing and sizing to help me find the best choice for me and my needs. I saw the young man tending to the outside, shows that they definitely take great care to make people feel safe. Great customer service! Will recommend to others! ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that SmartStop Self Storage - 4200 Westminster Avenue has to offer. These amenities include Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Security Camera, Gate, Parking, Credit Cards Accepted and Online Payment. 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 SmartStop Self Storage - 4200 Westminster Avenue can satisfy all of your storage needs. Different sizes here range from 40 to 348 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 SmartStop Self Storage - 4200 Westminster Avenue come at a variety of prices, starting from $103 per month for typically smaller units. However, larger spaces can set you back up to $774 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!
