Jay S. - 3 March 2026
Ryan N. - 20 February 2026
Super easy to move in and out both online and in person (Christine, Denville NJ). Very clean and well lit. Prices tiered. Near major highways. Plenty of space to park and move stuff in and out. Sometimes 1 gate is left up permanently so that’s not great but u need code to get in the building, so still secure. ... Read more

Mickey C. - 21 December 2025
Great experience! Courteous and friendly. Mike was very helpful getting us acquainted with the facility as this was our first time using a storage facility. He took us on a tour of the facility, gave us tips and tricks for navigating and moving our items in and out. He was also very informative of how to use the app to get in and out of the facility. Mike also assisted us with rental price agreements and broke down how future pricing would look. ... Read more

My wife and I have a unit in the building already and so have been very satisfied with it. We were looking to downsize to a smaller unit in the building and had the pleasure of working with Mike to get that done. He made the process so quick and easy. It’s always great when a place has great staff and service to go along with a great storage facility. Can’t recommend this place enough. ... Read more

I have been a client of Extra Space Storage for many years, and my experience has been always very positive. The location at 300 Morris Avenue in Denville, New Jersey is always impeccably clean, and the staff is always courteous and very helpful. In particular, I would like to highlight the work of Mike Turner, the manager of this unit. The success of this location is due in large part to his devotion to high standards. I am grateful to Mike for the respect and kindness that he always showed toward my Dad and I. I strongly believe that his efforts should be recognized and rewarded by corporate with a special bonus. I have used other storage companies, but none compare to my experience with Extra Space Storage. ... Read more

Great experience getting the storage space. Mike was very nice, explained things, took me to my unit and even wished me a happy birthday! Hallways are very well lit, there are carts at each entrance and it's easy to access. I highly recommend this facility! ... Read more

I was always treated courteous and if I needed someone, they responded immediately. It's always clean, IMMACULATE! And my property was safe and sound. Access is great. I have always felt very safe being there alone as well. I highly recommend this storage company. ... Read more
Karen S. - 2 May 2025
I recently visited the facility in search of a storage unit large enough to fit the contents of our home for an extended period of time. Mike greeted us with a smile and was truly a pleasure to work with. He took the time to explain all of the sizes available as well as the pricing for each unit. He personally showed us all the available units and answered all of our questions thoroughly. He made the process an ease. If you’re thinking about reserving a unit, do not hesitate to stop into the facility and chat with Mike, he was great. ... Read more

Sydney the Assistant Manager is down right AMAZING!!!! I give her 7 starts out of 5 for sure. She was so prepared and efficient and kind. Her listening skills are amazing and she followed up on every detail. Some examples include knowing my elderly mom felt more comfortable with paper copies, offering a senior discount and even greeting us as we occupied our RV space, with wise insight about how the sun might top off or battery while in storage! I am a middle aged man with a long extensive background in sales and marketing. It would not surprise me if this incredible prize of an employee ends up as a regional director someday. We are over the moon excited knowing that she is our point of contact as we store our beloved camper. Such a breath of fresh air. Thank You Sydney. Impressed, Mike and Cecilia ... Read more

Easy in easy out. I was moving in the same day. I’ve already been here a year. 5x5 10x10 and 10x 15 are the sizes I believe. In door and out door units. In door are climate controlled. There is some Rv, boat and vehicle outdoor storage. 6a - 10p access is helpful. Clean even the bathrooms are clean. Big elevators, Flat bed dollies, Boxes, packing tape, packing blankets, and plenty of space to store. My only complaint is I wish the doors to the elevator stayed open longer. ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Extra Space Storage - 300 Morris Avenue has to offer. 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 - 300 Morris Avenue can satisfy all of your storage needs. Different sizes here range from 24 to 400 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 - 300 Morris Avenue come at a variety of prices, starting from $43 per month for typically smaller units. However, larger spaces can set you back up to $827 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!
