Read some helpful reviews of Guardian Storage at 4635 Broadway, shared by real renters with genuine experiences and honest opinions.

Quintin K. - 28 March 2025
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
Victoria M. - 20 April 2021
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
W W. - 15 September 2014
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

Frequently Asked Questions

These amenities include Climate-Controlled, Indoor, Drive-Up Access, Retail Available, Onsite Manager, Truck Rentals, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted and Online Payment. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Guardian Storage - 4635 Broadway can satisfy all of your storage needs. Different sizes here range from 25 to 300 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Guardian Storage - 4635 Broadway come at a variety of prices, starting from $39 per month for typically smaller units. However, larger spaces can set you back up to $828 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
