603 Storage - Auburn

Lyndy Burnham

This service is as good in real life as it appeared to be online. I had a couple questions and called the number provided. I was greeted pleasantly and professionally and my questions were answered quickly and very much to my satisfaction. I immediately signed up online. There is a very impressive amount of back end technology being used by 603 Storage: my gate entry code as well as entry code to my interior storage building was immediately set - I could have gone to the building and storage unit and entered right away if I had chosen. 603Storage provides the lock for free (and lets you keep it when you leave). The facility was modern and in excellent condition when I entered. The very large unit I rented was immaculate - no dust or debris on the floor at all. There was a cart nearby which I was able to use to move my items into the ground floor unit. If first impressions are an indicator of what I have to look forward to, I am going to be very happy with my experience at 603Storage (in Auburn NH)!

**Edited review to include response from 603 Owner Mark Murphy** If I could give this company a 0 stars review for the way they conduct business and their unprofessional demeanor to paying customers (and employees) They treat their staff worse than they do their customers. Hence why almost all of their locations have extremely low vacancy. Please know if you rent with 603 storage you will deal with condescending, arrogant people who will talk over you and as if you are below them and tell customers one thing, and forget within a day later. Avon as 603 advised me I could transfer out of my current unit and into another (on a recorded call in which Mark was too lazy to listen to and then accused me of moving into a unit without renting, paying, etc.) and Dehamer (DM) backed Avon up when I asked her to forward the recording to the owners it magically disappeared—but I still have it on my end as this is not the first time this company says one thing and forgets what they have said the next so always, always document and record all conversations with them as they are too incompetent to do their own jobs. If you’re looking to do business with liars and bully’s, 603 Storage and Mark Murphy are it. I will continue to add and edit replies on here to inform our community to steer clear from these distasteful people. Do your research on 603 storage and Mark Murphy’s business history. Added review to show this type of behavior still hasn’t changed 4 years later…I’d love to see this company get shut down. Feel free to reach out to me to share experiences with 603 and Mark Murphy. Together we can spread the word and advise against.

I had a great experience with y’all. The staff is extremely knowledgeable and very friendly. The facility is great and very clean and well kept. There’s a wicked ease of access as well. Thank you guys for what you do.

The unit I rented is in a perfect location for me. I found the entire facility to be neat and clean. Someone took the time to sweep out my unit. Entry and exit is simple. The folks on the phone that I dealt with were eager to help and answer my questions. If you have to rent a storage unit I'd call these folks first.

It was so easy to rent from 603 Self Storage Auburn and they were so very accommodating, helpful and responsive, by phone, text and email. Plus their prices were very reasonable. I highly recommend
