    The staff was so kind and professional to me while I had used their storage unit space. Very helpful when I needed anything!

    Nice buildings but be aware they will give you a price to get you in the door but double it after 3 months.

    I originally had a great experience with right space till they got bought by this new company. They…read moregot bought out while I was overseas, they doubled the cost of the storage, and refused to put a military discount on my new lease. I got completely taken advantage by this company and their response to me was sucks. Even after I got home, they told me I could put all my stuff into a different storage unit to save money for the last two months I was going to be there but they would were going to keep my original storage unit 100 dollars more. Due to what this company did while I was overseas and how they treated me when I got back, I will never use a right space storage again owned by this company. I'm out thousands and their response to me is, well you could someone move all your stuff into another storage unit to make it cheaper while I'm overseas... outrageous... this company will not treat you as a human and will take every dollar they can from you.... Even leaving early, they will not give you your remaining of the month back... I will never use them again which is a shame, I did two other deployments and the last company completely took care of me. If your a service member, don't use this storage. When bringing up all of these issues to their management, they told me... sucks basically... don't let that happen to you!!! Very Respectfully, Timothy Gordon

    Great service! They returned our initial call promptly, were so friendly and pleasant and helped us…read morefigure out what size unit we needed. The unit was clean, the facility was convenient with 24/7 access and the price was reasonable. And they sell moving supplies at the office, which came in handy for some last minute packing. What more can you ask for?!!

    If you're homeless and want to rent a storage from Extra Space Storage and Dover on 6th Street…read moredon't bother! If you're homeless they will not help you or they'll let you move in of course they'll take your money and rent you a spot a space but the moment you're there for over more time than they would like you to over there when they think you're doing something when you're not or you're chilly first thing in the morning when you get here to go through your things to add more to it they assume that you're squatting when you're not because you're homeless and then they tell you to move out and take your money anyways so I suggest to everybody don't bother renting from them if you have any time a homeless issues because they will without a doubt pick on you till you leave the leaves or they kick you out ! Just because you come there to go through a few things and you take a chair out of your storage unit to sit for a few minutes to rest with your door half shut doesn't mean that you're squatting you should maybe take a minute and be compassionate and ask the person what they're doing instead of right off flipping out and assuming that they're up to no good or living in it ! It's sad that they don't take time for people that are homeless it's people like that in the world that make the homeless hard to be accepted in the world or helped in any way they give us a bad name for that very reason you no wonder why there's so many homeless in Dover cuz none of you give a crap or want to even take a second to be compassionate or understanding or any way give a helping hand I just hope everybody that works at Extra Space Storage on 6th Street puts their head down at night safely knowing that once again they have just unhelped somebody else and made them lose everything they own I hope you sleep good at night knowing you've done that and I don't care if my name is on this or what have you but they deserve every word I said only the good Lord judges you and you will be judged God bless everybody but six Street .
