Had a horrible experience unfortunately, just recently, because when this with ACE, they kept the place clean. At least cleaner. There weren’t any rodents, spiders maybe. Rodents definitely avoidable if they are on it like they say they are. Be sure to insure your stuff and sign up with THEIR insurance because they DO NOT take responsibility for anything. I’m not even sure they will even if you are on theirs. And I quote from their email from MP, “we offer storage specific property coverage to all of our tenants to provide that additional protection in the event that property loss is sustained.” So if you use your own insurance, because they do offer you the option to do so, basically they wash their hands, if something goes wrong. Quote from their email from MP, “Guardian is unable to provide you reimbursement for any losses being that our additional Protection Plan was declined at the time of rental.” So maybe don’t decline it and maybe they will help if you run into an issue. Maybe, I really don’t know and I’ve lost trust so do so at your own risk. Also seems like people may be living out of their storage units, possibly not staying the night but definitely eating there hence the rodent situation. Makes sense during hard pandemic times. But I wasn’t informed this was a possibility it may be happening. It seems incognito to me for them to not send a general letter or reminder that you shouldn’t store food or be living out of a storage unit. They should have been on it like they keep repeating they have, I never received a letter or reminder regarding this. I’ve been there a while and experienced this rodent issue just recently. For the price that they charge, you’d think this wouldn’t be an issue. They pride themselves on such high standards but they are not transparent, they inform you last minute of ‘repairs’ so you may or may not have access to your unit anyway. And they don’t offer dumpster service which is the least they could do. I trusted them with my belongings and they didn’t provide the experience they pride themselves on unfortunately. If their customer service wasn’t so much like ‘who cares’ my review may have been different but that would be me not being transparent. This is my experience and I’m telling it like it is. Still grateful but super disappointed my experience went downhill. Have since given them notice to vacate. Hopefully this helps in helping Guardian Storage be more transparent with everything and having more empathy with tenants from the beginning. After all, paying tenants are their paychecks, right? Be transparent with your tenants. You’ll be more successful… just saying. ... Read more

Great customer service. My lock had accidentally been cut off when the door was replaced and the staff in the office replaced the lock without question. I am impressed. The unit was fine, no leaks, rodents, etc. so my personal effects were in good shape after being in storage for over a year. I would use them again. ... Read more

Very clean property with amazing customer service. They are always helpful and respectful. Great rates and deals as well! I love that there are 2 entrances so there is never traffic getting in and plenty of paths so you can get any vehicle or truck in! ... Read more

I rented two units for a year and 1/2. They managed to get me two right next to each other. They were friendly and available whenever I needed anything. I had easy access to my stuff and it was not damaged at all in the 2013 flood. The unit was clean. When I moved out of the first unit they credited the partial month payment to my other unit. I didn't have to give a month's notice to move out. They were GREAT. ... Read more

ACE worked out great for me. Very simple, very professional, very friendly. They even credited me my last month when I moved out the day my payment auto-renewed having erroneously believed I still had a few days. Very nice customer service. ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 12 to 350 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient.
