Read some helpful reviews of Extra Space Storage at 1229 US Highway 22, shared by real renters with genuine experiences and honest opinions.

They do NOT take care of long time tenants. Have been there almost 5 years, currently paying $256 per month. Insane. The same unit is currently going for less than $100 for a new customer when reserved online. When I brought this up they first told me they would get my rate down to the wall-in rate, around $125. Check back 2 weeks after this conversation and I see my next payment is still $256. I then go to the live chat on the website. Live chat tells me the manager of this location will call me in the next couple days to discuss. The manager did call me, however I was only offered a discount to $205 per month. Still more than double what they are offering to new customers who reserve online. I will be taking my business elsewhere. ... Read more

Extra Space storage has dirty, dis functional, mediocre facilities and unhelpful staff. There were multiple times during our 13-month use of this facility that the elevator was broken and we were unable to access our unit. We saw no prorated amount or discounts applied to our bill during those times of extreme inconvenience. Also, the price had been raised multiple times during our brief period, to the point that I was paying more than 1.5 times the initial monthly cost I signed up for. When I asked a staff member for assistance and clarification regarding this, they offered no help, explanation or apology, instead promising to call me back within 1-2 days to see if they could rectify this issue (they never called). Avoid this facility at all costs. ... Read more

We have had the pleasure of using Extra Space Facility for many years. They have always be amazing and understanding when we needed the locks to be cut because we had lost the key. Brena (the store manager) was amazing and very helpful when we were clearing out our unit. ... Read more

They will double your rate after 3 months, and god knows what they gonna do after 6 months. This is how they sneakily take ur money, after ur all set and all comfortable and are used to their auto-charging notifications (so comfy that you will never bother to look into it to see how much you are actually charged for next month!!), they will start doubling your rental fee. If it wasnt for me checking my bank statement, I wouldnt realize they started charging me $105 since 2 months ago already, instead of the normal price $52, I really don't understand how things like this can be done so shamelessly and publicly and LEGALLY. They lured you with low price and when it's time they will rip you off real good buddy. ... Read more

These amenities include Climate-Controlled, Indoor, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Elevators, Multi-Level Storage, Online Payment and RV Storage. 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 Extra Space Storage - 1229 US Highway 22 can satisfy all of your storage needs. Different sizes here range from 20 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 Extra Space Storage - 1229 US Highway 22 come at a variety of prices, starting from $37 per month for typically smaller units. However, larger spaces can set you back up to $733 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!
