Stephen M. - 14 October 2026
I just want to give a big shout out to the crew over at Extra Space Storage on heritage in Portsmouth New Hampshire. This has been the best experience I have ever had with the storage facility in this area or even in Texas for that matter. From the initial selection process of my storage unit online, to the actual move-in process, they made it very easy and efficient. The motion lighted hallways, we're always very well lit as you enter the building and the lift elevator and cart were a big plus for me especially because it's hard for me to lift items up and down. Always clean and fresh smelling! My interactions with customer service we're wonderful but I must admit it would have to be the property Personnel that stood out the most for me. Always polite very welcoming and professional! If I ever need storage again this will definitely be my first and Last Choice. Thank you Extra Space! I rented a 5x5 for reference. Very reasonable pricing ?? ... Read more

Timothy B. - 11 August 2026
Very helpful and accommodating. The employee explained my contractual obligations to me thoroughly and answered all my questions. Prices were comparable. People were nice. Space was clean.

Extra Space Storage Portsmouth - love them. Having relocated from Canada from two residences this Storage company has been top notch. They have a phone number and someone actually answers it!!! Seriously when your credit card expiry changes , you need someone to contact and change it. The prices are fair and the customer service exceeds expectations!!! We have never had issues entering the lot. I highly recommend!!! ... Read more

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

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
Kristen F. - 3 September 2025
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
El S. - 31 July 2025
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!

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
Nancy M. - 30 April 2025
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
Todd D. - 16 April 2025
I have had several conversations with both Erica and Matt At extra space storage. They are wonderful to deal with always kind and explain everything. Additionally, willing to work with you to get a positive result. Always come back from speaking with them on a positive note! Great company to work with!! ... Read more
Kathie L. - 3 April 2025
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

I appreciate great customer service and the office staff has consistently provided me with it!
Their professionalism is top notch and I have always had a positive experience with staff members. I have been renting a unit for a few years and am pleased with the security, ease of access and equipment available when needed.
I would highly recommend the Portsmouth location! ... Read more
Julie M. - 21 March 2025
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
