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

    Been at this location less than a year b/c it was affordable compared to the other place we were using. They raised the rent for both our storage unit & RV storage 30% without notice. This is ridiculous. We will be finding another location. ... Read more

    JUNK YARD! With the dumbest manager you will ever meet. Moving in less than a year ago was a huge hassle and they kept trying to overcharge us, spent countless hours chatting and on phone to correct. Here less than a year and we get notice our rent is going up 50 a month but when you go online the same units are going for 50 less a month. Gave notice of move out and they are still trying to charge me. FIND SOMEWHERE ELSE, THIS PLACE IS HORRIBLE! ... Read more

    Here less than 1 year(8 months) and we get a notification that they are raising rent. So we find an another place that's gonna save us $100 a month and does pest control(this place has tons of rodents fyi), and they won't reimburse the rent I paid for this month. I was told when I went in last time that it would be. Leaves a bad taste when people are comfortable keeping money like that. Won't be back and won't recommend. ... Read more

    It's a great place, good location and very secure, we've used them for tha last 15 years, never had anything messed with or stolen, unfortunately their space rent prices continue to climb and I can no longer afford it, so this my last couple months with them. I recommend em though if you need a good secure place to store your items, I used the outdoor rv space for the majority of the time, they offer several different size lots or units, indoors or out ...

    Over the past 10 years I've rented two storage units plus a parking space for my RV. Everything is very clean and secure. Service always has been friendly, helpful, professional. Completely pleased, zero complaints. Look forward to using them again ?? ... Read more

    Getting the storage unit was simple. I did it all online and it only took a few minutes. Even got the first 2 months at a nice discount doing it online. Then I went to the mini storage location and got my access code and finished the process. The lady there was very nice and finished the process quickly. ... Read more

    Worst storage unit ever! They doubled the price I was paying within a 3 year time frame. It went from $90 to $180. The office lady was so rude when called and told her we wanted to cancel. And continued to be rude until we moved our stuff out. This place is a complete joke! Don't rent from here unless you want to get ripped off on price and by thieves that break into units on a regular basis. ... Read more

    Terrible customer service and lack of professionalism. Moved out on Feb 18th and notified office I had taken my lock off. Although there is a 30 day notice they would not give me a receipt that I was out and lock off. They said they would pro rate but billed me for full month of March, $336, outrageous. Still have no paperwork saying I moved out. Called corporate and customer service, Grant said they should have vacated me. Still no paperwork. Terrible business. If I could give a negative number in rating I would. Interesting they have a lock on the space they say I have till March 10th? Did they rent it out on my dime? Definitely not an honest business. Beware! ... Read more
