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

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

This particular storage facility provides self storage units of different sizes, ranging from 24 to 400 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 - 300 Morris Avenue start from $37 and can go up to $902 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.
