This place is absolutely terrible. I won an auction today and called the number on the invoice. They told me they were open until 6 PM. I asked for time off from work, drove there, and arrived at 4:45 PM — but the office was closed. None of the phone numbers were answered. Even the main company number tried to reach the employee and told me he was already gone for the day, even though the sign on the door clearly says open until 6 PM. There was no other information available. I cannot come at another time, and I specifically asked in advance about the hours. This is completely unprofessional. I do not recommend dealing with such irresponsible people. ... Read more

I can’t say enough great things about Life Storage! Their customer service is truly top-notch, from the moment I walked in, I felt valued and well taken care of. They go above and beyond to ensure that your belongings are safe and secure, and the facility is always clean and well-maintained. Anthony, the store manager, is exceptional. He not only takes time to make sure every customer is satisfied, but he also remembers your name and treats you like family. It’s rare to find that level of genuine care and attention. If you’re looking for a storage facility where your items and you are treated with the utmost respect, this is the place. Highly recommend! ... Read more

From the moment I arrived, he was incredibly attentive, patient, and professional. He clearly explained everything, helped me choose the right unit for my needs, and made the entire process quick and stress-free. It’s rare to find someone so dedicated and helpful. ... Read more
Raphael D. - 17 June 2025
Extremely Disappointed – Be Cautious Before Signing Up My experience with this company has been incredibly frustrating. Within my first three months, they doubled my rate. When I reached out to ask why, their response was basically, “No problem — we’ll just raise it by 10% instead.” Six months in, my rate was hiked again — this time by nearly 90%. They’re great at texting and emailing receipts when it’s time to charge you, but when it comes to price increases, suddenly it’s a mysterious “letter” that somehow never shows up. Both times my rate was raised, I never saw any clear communication in advance. Overall, it feels shady and disrespectful. If transparency, consistency, and trust matter to you — I’d look elsewhere. ... Read more

These amenities include Climate-Controlled, Indoor, 24 hour access, Drive-Up Access, Retail Available, Onsite Manager, Truck Rentals, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, 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 - 9900 SW 18th Street can satisfy all of your storage needs. Different sizes here range from 24 to 250 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 - 9900 SW 18th Street come at a variety of prices, starting from $7 per month for typically smaller units. However, larger spaces can set you back up to $510 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!
