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

Outstanding service from Antony! I had an amazing experience at Extra Space Storage thanks to Antony’s exceptional service. 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

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 24 to 250 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 Extra Space Storage - 9900 SW 18th Street start from $8 and can go up to $662 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.
