I rent a 5 x 5 storage unit at the 70 Heritage Ave. Portsmouth, NH, 03801 location. I have been in one of their storage units for going on three years now. I am very happy with the service that they provide for me. I’m Even more happy that when I have any inquiries or grapes, that they address them right away and accommodate me in whatever way I need. Therefore, this is why I wanted to leave this review to Express my loyalty and admiration for Extra Space Storage. Specifically in Portsmouth, NH 03801 09/28/25 I am confused because my $38 monthly payment has now gone up to $50 when I spoke directly to someone who guaranteed me the same amount... ... Read more

Nothing but positive experiences with Extra Space Storage - nationally. Both in SC for my college kid’s summer storage but especially in Portsmouth NH! The Heritage Ave location has been so professional and accommodating - even got a free storage box today! Super easy with code and almost 24/7 access and the units / buildings are so clean. Always someone driving around when I’m there, too, so feel both me and my stuff are safe! ... Read more

We’ve rented dozens of spaces with Extra Space Storage over the years. We’ve had as many as 23 units at a time. We’ve watched the facility transition from Heritage Storage to Life Storage, and then finally to Extra Space. The service is spectacular. The people there are incredibly reasonable, down-to-earth folks. The online portal and payment systems work great, too. I’m unsure how one could improve in the storage industry: zero complaints, only praise. ... Read more

I "reserved" the size unit I needed ahead and did my reservation online. The day arrived and there were a few questions I needed to ask. Although I was reserving in Concord NH the general number linked me to another NH location; Portsmouth NH. I spoke to two agents; Thomas and Erica. Both helped me to navigate the online app as well as clarified any questions I had. Great attitudes! Very helpful! And Erica got all my paperwork fine tuned the day before I needed access. Very good customer service. Excellent promo pricing! Thanks Team! Jean S., Concord NH ... Read more

I have been so happy with the customer service in the Portsmouth NH location. Thomas, Matt & now Erica have been wonderful to work with. The company itself has policies that are less than desirable. The price on the unit I was renting went up in price from $95 to $200. If it were not for Thomas, Matt and Erica I would have moved out. Instead they found a unit upstairs in the same building that was in my budget. Thank you so much to them for their professional and gracious handling of the situation. ... Read more

The managers and staff are super friendly and helpful! The automatic gate and fencing gives me peace of mind that the facility is secure. I have had a great experience renting there. What’s even better is that I was able to lock in an affordable rate by paying for the whole year up front. I definitely recommend the prepayment option if you know you’ll use your unit long- term. 5 stars ?? ?? ?? ?? ?? ... Read more

Worst and shadiest business I've ever dealt with, and awful unapologetic customer service. I originally rented their smallest unit to store a few things for a couple months. When I inquired as to why they withdrew over $200 from my acct. over 2 separate withdrawals spanning 3 days recently, I was told that my rate was recently DOUBLED from one month to the next because “Oh you had the special internet rate (whatever that is) for the first 3 months and then it goes up. It goes up? You doubled the price with no prior notice! Save a sub clause line in a book of a contract that they quietly slip by you and then start direct withdrawals. No one informed me the rate would be changing. For a tiny 5x5 unit the price is ridiculously high once they get you in. This is a scam and a predatory business. Preying on people who need interim help as they make changes in their lives, and I know they will delete this review from Google but hopefully at least even one person sees it and it an save them from being taken advantage of by thieves and charlatans. You’re carnies. ... Read more

I stored my motorcycles at Extra Space Storage in Portsmouth from November to March, and the experience was excellent. The facility was clean, secure, and well-maintained, giving me peace of mind throughout the winter. Access was easy when I needed it, and the pricing was very reasonable. The staff was always helpful, making the whole process smooth. If you need a reliable place for storage, I highly recommend Extra Space Storage! ... Read more

Can’t say enough good things about this place. From staff like Tom, Sam, and Matt, you know you’re taken care of period. While I’m there, I feel very safe even late at night and knowing my inventory is secure, it frees up bandwidth for me to focus on what really matters. Other reviews are right on the pricing being great, but that’s the least of what makes this place the undeniable best location for storage on the East Coast! Five stars all day ... Read more

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 - 70 Heritage Avenue start from $30 and can go up to $378 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.
