    They do NOT take care of long time tenants. Have been there almost 5 years, currently paying $256 per month. Insane. The same unit is currently going for less than $100 for a new customer when reserved online. When I brought this up they first told me they would get my rate down to the wall-in rate, around $125. Check back 2 weeks after this conversation and I see my next payment is still $256. I then go to the live chat on the website. Live chat tells me the manager of this location will call me in the next couple days to discuss. The manager did call me, however I was only offered a discount to $205 per month. Still more than double what they are offering to new customers who reserve online. I will be taking my business elsewhere. ... Read more

    Extra Space storage has dirty, dis functional, mediocre facilities and unhelpful staff. There were multiple times during our 13-month use of this facility that the elevator was broken and we were unable to access our unit. We saw no prorated amount or discounts applied to our bill during those times of extreme inconvenience. Also, the price had been raised multiple times during our brief period, to the point that I was paying more than 1.5 times the initial monthly cost I signed up for. When I asked a staff member for assistance and clarification regarding this, they offered no help, explanation or apology, instead promising to call me back within 1-2 days to see if they could rectify this issue (they never called). Avoid this facility at all costs. ... Read more

    We have had the pleasure of using Extra Space Facility for many years. They have always be amazing and understanding when we needed the locks to be cut because we had lost the key. Brena (the store manager) was amazing and very helpful when we were clearing out our unit. ... Read more

    They will double your rate after 3 months, and god knows what they gonna do after 6 months. This is how they sneakily take ur money, after ur all set and all comfortable and are used to their auto-charging notifications (so comfy that you will never bother to look into it to see how much you are actually charged for next month!!), they will start doubling your rental fee. If it wasnt for me checking my bank statement, I wouldnt realize they started charging me $105 since 2 months ago already, instead of the normal price $52, I really don't understand how things like this can be done so shamelessly and publicly and LEGALLY. They lured you with low price and when it's time they will rip you off real good buddy. ... Read more
