Read some helpful reviews of Extra Space Storage at 1000 Route 11, shared by real renters with genuine experiences and honest opinions.

The experience couldn’t have been better. From finding the location, to reserving and paying, to downloading the app to get into the gate, to finding my unit ready with a new lock. Perfectly easy and smooth! ... Read more

I do NOT recommend. I was told there were no special move in offers, and that the price would not change within a year. I SPECIFICALLY asked about this at move-in. They also told me they would call me the next month as they would have a bigger unit opening up that I needed. They never did. But they raised the price knowing I was out of state and could not readily easily go back quickly and consider options-which I discovered in my credit card bills (no phone call, no letter, no notice) Get ready for a bait and switch. Moved my things elsewhere as soon as I could! Also while trying to program my combo lock which I purchased there, the staff kept trying to "do it for me" and see my combo code. Be CAREFUL! ...

I’m extremely happy with Extra Space Storage in Sunapee, NH. The property is secure, very clean and is easy to access especially in winter. I also appreciate that the property is staffed during the day. Greg has been so helpful there! He worked with me to get the best competitive rates and helped me when I needed a bit more space while in transition. I have referred two more friends since I started renting there because it’s such a great place to securely store items as well as having friendly helpful staff on site. ... Read more

Frequently Asked Questions

Storage units available at Extra Space Storage - 1000 Route 11 include the following amenities: Climate-Controlled, Drive-Up Access, Retail Available, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Online Payment and RV Storage. 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 25 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 - 1000 Route 11 start from $63 and can go up to $362 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.
