    Read some helpful reviews of Extra Space Storage, shared by real renters with genuine experiences and honest opinions.

    I take back all the good things I said. Getting the storage was a great experience. Since getting it, I have been bombarded with spam requests asking for a review, that I already did. And on top of that, when I went to actually use my storage, THEIR lock was still in it so now I have to wait until Monday... when I work, to start moving things in. Thank you so much for providing the most frustrating and inconvenience week of moving that I will ever experience ... Read more

    I have been a storage unit user for more than 15 years all over washington from Marysville to spokane to Woodinville. This has been by far the worst experience I have had dealing with a facility. The first day I moved my stuff in I was INSIDE the building when 8 pm came. With no warning I got locked out, unable to get to my rental vehicle, tried to find staff, called the main extra space storage line to get to my rented vehicle and while I was talking to them for help there was an announcement that if I did not leave they would call the police! The manager is condescending as heck when I tried to move out. And will not even recycle the locks they force you to buy, I've literally never in my life seen the types of locks they use except through them. If I am not returning and you can't resell it (even though I couldn't get back into the facility with no pass code but okay) you could at least dispose of it. Waste of money. Waste of time. Not worth the emotional whiplash. Gave a star because the building was clean. Thats all it had going for it. ... Read more

    Dont buy storage unit from this place. The manager is absolutely horrible waited outside for an hour and was told by many consumers this was normal. After Cleaning out within the 48 hour window wasn't a problem. The problem was i go get my deposit back. He said its been to long (3 weeks) and they werent going to refund me. So they just stoled my money even tho nothing says you have go back within a set time frame on the receipt or on the website. ... Read more

    ???????????DO NOT GO HERE. THEY WILL LIE TO YOU ABOUT THE PRICE. They are basically scammers. Last year in May of 2024 I called around to find the best price in Federal Way for a storage unit. On the phone they told me it would be $87 a month for a 10x15 unit. I asked them if this was a promotional price - considering it was almost summer. They said no, it's not a promotional price. I asked them if my price would be guaranteed to stay the same. They said yes. I decided to move all my stuff in. 2-3 months later I get a notice that my storage unit bill would be going up to $182.50 a month. That is more than double what I was paying before. If you do decide to go with this business anyway, I highly recommend to get EVERYTHING in writing. Do not believe a word they say. Also, the building my stuff was stored in there had constant issues with the electronic door (to get in and out of the building) and we have been stuck inside and had to wait for help from one of the employees to open it. For anyone reading this that is already a customer of Extra Storage Space, remember in the state of Washington storage unit facilities are legally required to provide at least 60 days written notice before increasing rent. Know your rights!!!! EDIT: the business has now responded with more BS and lies. You do not strive to provide clear communication. You strive to make as much money as possible, no matter how ethical or unethical. I never received a physical copy of my rental agreement so I'm not sure how you expect me to review it. ... Read more

    Shelby and Nat were very helpful when we needed to move from a smaller unit to a larger one. We are downsizing and Shelby even helped us visualize how our household items would fit in the unit so we could choose the right one. From our experience, the facility is well kept up, clean and secure. ... Read more

    When I first arrived at the office, I was warmly welcomed, which made me feel great. I was also amazed at how impeccably clean the entire building was. Moreover, everything was explained in a very kind and easy manner, and they even walked me through the process to confirm everything together—how could I not be happy? ... Read more

    At first it was simple, easy process to sign up. Our rate went up 2x. Way to expensive for what you are getting. Can be crowded and hard to get parking or get a cart. Elevators have been broken down mutiple times. And since "fixed" the elevator takes 5-10 secs to realize it's on the floor you need to be on at open it's doors. Now trying to get out the storage space and get a pro rated monthly charge. The office manager is rude and does not care and does not want to help. We asked for his supervisor and will not give the contact information nor any information. Gives excuses to keep your money.He says the opposite from what the customers service reps said. That we can get a pro rated monthly charge. In my experience here, I would suggest taking your money somewhere else. He seems like he needs a career change and not be in a customer service type role or manager for that fact. ... Read more

    I had an excellent experience with Extra Space Storage! The facility is clean, secure, and well-maintained, making it a perfect place to store my belongings. Brian, the manager, was incredibly helpful and friendly. He went above and beyond to ensure I understood the process and made sure I got the best unit for my needs. His customer service was outstanding, and he truly made the whole experience stress-free. I highly recommend Extra Space Storage for anyone in need of reliable storage solutions! ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.
