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

Storage units available at CubeSmart Self Storage - 4121 Sienna Pkwy include the following amenities: 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. 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 300 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 CubeSmart Self Storage - 4121 Sienna Pkwy start from $38 and can go up to $377 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.
