Rick was so helpful. I ran into a situation where I left my keys at the office and we could not find them and despite me being anxious, he kept calm and checked every area and found the keys. He explained to me that my lock was not on correctly and could have some issues, and when I asked for help, he happily followed me to my unit to make sure I could get incorrectly. I have never used a storage unit that has such helpful members, and I was very appreciative . ... Read more

I originally had a great experience with right space till they got bought by this new company. They got 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 ... Read more

Smooth, online rental agreement. Representative was extremely knowledgeable and patient with our questions. Went to the office prior to moving our stuff into the storage unit just to get a lock. Staff member was so helpful and even came to the unit to assist us with our questions (twice!) Definitely recommend the Dover location and RightSpace in general. ... Read more
