The service here is exceptional. Tom was very professional and friendly and provided us the best options for what we were seeking. I’m pretty sure we came into the office very close to their closing time but he didn’t make us feel like a bother or rush us at all. We really appreciate that! ... Read more

Chelsea M. - 5 February 2026
I have had a storage unit at this site (Sienna Pkwy) since it was built. And, in the past 35 years, I've had the opportunity to patronize a multitude of storage facilities. So, I view myself as somewhat of a discerning expert. Let me be clear: The reason that I CHOOSE to remain a customer of this specific CubeSmart Self Storage location is because of the manager, Robert B. Simply put, he is an unbelievably kind, customer-driven, blessed, magnificent human being. Under his leadership, the facility is always clean, very well-maintained, and very secure. Take those factors into consideration and add Robert B. into the mix and the result is EXTRAORDINARY EXCELLENCE beyond your expectations. THANK YOU, Robert, for an extraordinary job outstandingly well done!! And, I'd be remiss if I didn't acknowledge the kindness of Tom G. What a phenomenal team!! Dr. R. ... Read more

Honestly the smoothest move in for storage I’ve ever had. The staff is super friendly and helpful. I was confused on the map and he came and brought me to the unit and showed me how to use the lock. They have dolly’s on every floor so move in was super quick. Highly recommend this location!! ... Read more

Very friendly lady at the front desk! She answered all my questions, showed me to my storage unit and even wished me luck on my travel plans for work! Location is very safe and clean. Even provided storage carts to make my move easier. Update a year later and updating stars. After 3 months of having my items in storage I entered to find it infested with spiders and dead ants. I mean they sprayed and there was a layer from the ceiling of dead ants covering all of my boxes and items. Ants are seen running around the outer areas of the “new building”. Problem is the newest building added is really in a used to be wooded area so the units get infested with insects. I immediately told management and they did not believe me. Finally I got someone out to see and they started sweeping, spraying and helping me clean. It was so bad I spoke to management about moving to another unit. Management only discounted me half a months rent (which they increased over $60 2 months later because of the new year and higher rates) so I basically got barely anything taken off my bill and they wanted me to just shut up. The white gentleman that’s a manager is just plain rude and not helpful. Eventually my dad and I (had to get a man for them to listen) spoke with them and they agreed to move me to a unit that would be clean. Only available unit was across the entire property and no they did not pay for movers or assist with moving my items even though their negligence caused my items to be infested. Best we could do is get manager to come moving day so he could see how bad it was. He literally vacuumed every box all over because of how bad the giant spiders were and did not apologize once when it was worse than he thought. At this point I took 1 box home because I was starting my work assignment the following week out of town. Talk about short notice that I happened to visit before I moved away and found my items in disarray. That one box had at least 3 spiders inside when I opened it on the porch of my parents house. Since then I’m in building 1 that seems cleaner and safer. Although with hurricane beryl there was no power and items may have gotten further damaged. At this point I avoid going because I don’t even want to deal with issues. Hoping my stuff is safe and wanting to get my items out asap. Will need a steam cleaner for couch, mattress and will likely throw away overly infested items. You think the storage will compensate me? Nope. My items were all brand new (less than a year old) and now I’m not sure I feel comfortable even laying on my material couches that could have spider eggs and ants inside. Another update. If I could give 0 stars I would. Since beryl my items have mold and mildew. All wood is damaged extensively and insurance refuses to pay out. Manager also refuses to help. Waiting on district manager to resolve issue but it’s been about 2 months with no resolution. Here are new photos of my damaged belongings. Natural wood items are covered with mold. Even wrapped items too. Manager confirmed no power for 5 days and temps reached 81 degrees. Talk about temperature controlled. Unit prices have only gotten more expensive. Started at $240 and now $350 a month and most of my brand new items will be trashed and replaced. Thanks for taking care of my items cubesmart. Never again. ... Read more

I had the best experience renting a storage unit from this location. The staff was very friendly and helpful. The facility is very clean and secure. The staff walked through facility with me, showed me how to use the lock, and also explained in detail how to access the property and manage my unit. I definitely recommend renting storage space at this location. ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that CubeSmart Self Storage - 4121 Sienna Pkwy has to offer. These amenities include Climate-Controlled, Indoor, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Elevators, First Floor Access, Multi-Level Storage 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 CubeSmart Self Storage - 4121 Sienna Pkwy can satisfy all of your storage needs. Different sizes here range from 25 to 300 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 CubeSmart Self Storage - 4121 Sienna Pkwy come at a variety of prices, starting from $38 per month for typically smaller units. However, larger spaces can set you back up to $374 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!
