Guardian Storage - Superior

Superior CO 800276.4 miles away

4 out of 5 - Based on 9 reviews

Starting at $176.00

PROCESS: it was very easy to understand the product options from the website, then easy to reserve a unit WITHOUT having to give a credit card, then quick followup phone call came in, then straightforward phone call with service person answering a couple questions, then all the lease paperwork was done in a few minutes online, including online signatures, then quick followup with detailed instructions for moving in ... that whole sequence took maybe 20 minutes, including back and forth sending of links via email. So, a very good purchase and signup process. PRODUCT: it's a storage unit, so not something that's very complicated, but everything you'd want was available ... easy custom code to access the property, new buildings and very clean interior hallways and inside of unit, and there were handtrucks available to help move items from car to storage space, and a simple/basic lock to secure the space. ... I'd recommend Guardian to other people.Full Review

So I needed the office to call me back at 1130 today and didn't get a call back. Anna working there just essentially told me, tough luck in her email. The Manager, Melissa was made aware and didn't fix the matter. So I'm left to just leave the review.Full Review

There was a bit of wait to wrap up paperwork (office was full of people checking out for the end of the month) but Brian C. was really friendly and helpful. The place was clean and has good access hours.Full Review

I had booked at another location and then found an apartment closer to this. Both location was very helpful in transferring my booking to this. The manager who checked me in was extremely nice and helpful. She even answered my questions that had nothing to do with storage. The bathroom and the entire place was immaculate, so much so, that I thought they had just opened up the location, then I found out they have been there for almost 3 years. I will definitely recommend them and if I need a storage unit again they will be my first stop.Full Review

Great customer service! Well maintained and staff was very helpful!!!Full Review

I shopped three different storage facilities in my area and Guardian Storage was the winner. Great price, service, and value. I took advantage of their free truck and was able to get my two bedroom apartment packed and loaded in one trip! Outstanding. I received my 1st Month free and got a locked in rate. I would have like to have known there was an additional prorated charge for entering in the third week of the month, but other than that I'm a completely satisfied customer. Outstanding staff!! I highly recommend.Full Review

I had a storage unit here earlier this summer while preparing for a move. It was a fantastic experience. Now that we are settled into our new, much downsized home, we had a need to store some items that we just don't have space for. There wasn't even a question in my mind where I would choose. The pricing is extremely competitive and the helpfulness of the staff can't be beat.Full Review

I was originally interested in this company because of the low prices of their storage units. I called the office to ask the Manager a few questions, and she was incredibly friendly and eager to help. After asking my questions, I quickly reserved a unit. I live in Boulder and am not familiar with Broomfield, but the place was easy to find. The facility was well maintained and I was greeted as soon as I arrived. The same manager showed me to my unit and helped me with my paperwork. She was incredibly personable as well as professional. I would highly recommend this company to anyone looking to store their things!Full Review

I cannot remember the ladies name that helped me on Thursday when I signed my lease at the Sugar Bin Storage but she is AMAZING. I made an online reservation and came in later that day to fill out paperwork and make a payment. When I arrived she has all of my paperwork ready and easily accessible. She did an amazing job at explaining the costs as well as the lease agreement. It was very quick but efficient start process. She was friendly and brightened my day. As this is all new to me she made every step a lot easier. I will always rent from here as well as recommend this storage. Thank you!!Full Review
