I was renting at Public Storage on Fox street and made several complaints about a rodent problem. So in my search I went to the ESS location on Grant Street and Evette and Allison talked me through their policies and showed me the facility. They were very helpful and knowledgeable ! 10/10 service ... Read more

I can’t recommend this Extra Space enough - Alison is AMAZING and endlessly helpful. She made a stressful time that much easier, and made sure I had the storage size that was right for me. She was also readily available and responsive. Get your storage unit here! Thanks Alison! ... Read more

I had the pleasure of visiting an extra space storage with my boyfriend last week. When he came into the office today I was pleasantly surprised on how fast the process was. We had some other things to take care of today so the fast, quick, easy lease was exactly what we needed. Thanks to Allison and Zendae for helping us with this. 10/10 best experience I’ve had with a storage company. ... Read more

Allison went above and beyond for me when I moved my things into storage a month ago. She actually stayed an hour past closing so that I could come set up the unit after work because of the pickle I was in. THANK YOU ALLISON!!

Facility is nice but after 3 months they doubled my rent. Went from $74/month to $158/month with less than 3 weeks notice Edit: I did call and they did lower it. To $105/month. That’s still a 35% increase after 3 months. At this rate I will be paying a mortgage to you in a couple years. I also want to point out that no value was added to me with this price increase. No additions to building, no extra services, no anything to justify the price hike other than business want so business take. Genuinely shameful business practice. I also want to be extremely clear that all employees I have spoken with have been extremely nice and helpful, it’s just unfortunate that they have to represent a business like this. One star is too many ... Read more

This is literally the best storage unit place in the entire city! This team is absolutely incredible… They will work with you, they will take care of you, even if you are in crisis, they will be understanding and help provide you with support and love. Please please please make sure you come here and see Francisco and Alison and Jessica and I promise you you will feel like you are family. I would not say it if I didn’t experience it myself and see it happening with multiple people in this building. We are building a community over here! Lots of love to you, can’t wait to see you over here on Grant Street!! ????? ... Read more

This place used to treat me really well under the old brand. Today I noticed they had quietly increased my rates 50% (!!!!!) over the last year or so. There must have been at least 3 separate increases this year alone when I started to go back and look. (They say they mailed the notifications but I never saw em and everything else is done by email so obviously the tactic is to slip it by unnoticed.) If it were a reasonable increase I wouldn't care. But quietly raising them every few months to a total of 50% is some real chef's kiss corporate behavior. I fell prey to the oldest trick in the self-storage book. Shame on us both, I guess. Edit: I did just call you. That's how I cancelled. I'm not sure what you want to discuss. If you'd like to refund me the entire amount above what I agreed to when I signed up, please go right ahead and do that. You have all my contact information so by all means utilize it if you feel a burning desire. ... Read more

I am updating my review. I’ve been a very happy customer for 2 years! I am so happy a family member (also a customer) told me about this storage facility. I now have two units here, and also have a friend who has a unit here. The place is very clean and secure. I feel safe dropping things off at night. The units are temperature controlled, plentiful carts, TWO parking lots with dedicated parking on both sides of the building, THREE large elevators, and sliding door entry ways that stay open long enough for you to situate your cart. It’s also very clean. After hours access is very handy. The prices are really competitive. The management is AMAZING. They will get to know you and are personable. They understand what you store is important to you. I’m very happy. ... Read more

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 20 to 300 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.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. 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. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Monthly prices for units offered by Extra Space Storage - 900 Grant Street start from $56 and can go up to $733 for larger spaces.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
