Friendly & helpful lady behind the desk.
I cannot say enough good things about Storage Company. The facility is excellent, but the highlight of my experience has been the manager Robyn. Her warm and welcoming demeanor makes every visit enjoyable. She is incredibly knowledgeable and always goes above and beyond to help. Thank you 128th Storage and Robyn, for your exceptional service!
Management was great and facilities are top notch.
EXCEPTIONAL customer service at this facility. I worked with Robyn, who was kind, helpful, and fun to be around. She made everything so easy. The facility is super nice. Highly recommend this facility for any and all storage needs. I will definitely be using this facility again, and recommend it to all family and friends. If I could give more than five stars, specially for customer service, I would. Thanks Robyn!
Longtime Renter, Units and Facility are always clean and secure. Staff in the office is always helpful and nice to deal with. Highly recommended if you need a place to store your stuff!
Great and friendly customer service. The office manager, Robyn is always to helpful whenever I need any assistant. Thank you!
We have had the opportunity to rent storage twice from this facility. Luckily Robin has been the on site rep both times. She is fully knowledgeable and always ready and able to do her job quickly and professionally. And what you can't teach, she is just a nice person. The facility is clean, well maintained and secure. Refreshingly nice experience compared to so many others not as good.
Response from the owner: Thank you for the 5 star rating!
Very happy with this storage facility. The storage unit was cleaned out and ready to go when we showed up. The staff was very helpful and professional. Super easy to deal with never once had a problem entering or exiting the facility. The manager Robin was always on site and very helpful If you need anything. We were very impressed. I would definitely recommend this storage facility to anyone and we will use them in the future if ever need be.

I LOVE THIS PLACE! It's CLEAN!!! Safe and also private. I've done many storages and the way the ladies keep this place super maintained and organized is such an awesome plus. Not just that, YOU CANNOT BEAT THE PRICES!!! The hours are great from open to close and if you need anything, they attend to it ASAP! I'll be here for a while!
Moving Nextdoor is a big fan of this storage facility! We come here often for our clients, and it's always clean and the staff is friendly.We Recommend!
Excellent self storage facility.
Friendly people and clean units - exactly what I need.
Response from the owner: Thanks for the great review Chris! We appreciate your business.
This was the easiest self storage I have used! As a Realtor, i sometimes get storage units for my clients to help with their move. Robyn was awesome to work with and gave good customer service to me and my client was very happy with the unit and the security she had during a very long move. They were waiting on a new build and had to rent back their house for 59 days. This meant putting a lot of stuff into storage to make it easier for the transition. Easy to move in and easy to check out without having to fight charges some units charge. I will recommend this storage solution again! Thank you!
Response from the owner: Thank you for the excellent review Bruce and for referring us customers! Our family owned company prides ourselves on providing a great storage experience. We appreciate and value your business.
This is hands down my favorite storage unit I have ever used!! Staff goes above and beyond in all aspects for the costumers. I came into this unit the first day fuming mad from another storage facility. The manager took me with a grain of salt and by the time I was done filling out the paper work she had me laughing. The Prices are great for Colorado, and the few times I have had to talk with the office it has been a great time. I will always use 128th self storage! Great job!!!!
Response from the owner: Thank you for the great review. We’re happy to hear that you had a great experience that reflects the priority we place on providing a great customer experience. We appreciate your business!

Very friendly, quick and clear no touch sing up and rental.
Response from the owner: Thank you for the great review! We appreciate your business.
Reasonable prices and a very safe and secure location. I was able to go in and out as needed and wasn't affected by the lock out times. I think it's ok to have a period of time where nobody can enter for the safety of everyone. Never had any issues with management and they were very kind and easy to work with. I recommend using them over another storage facility.
Response from the owner: Thank you for your 5-star review Fuad! We've worked hard to provide a safe and secure storage experience for our customers and are happy to hear this reflected in your experience. Thank you for your business and recommendation!

Excellent customer service and decent prices. The facility is new and the storage units have vaulted ceilings. More than enough room in their 10X20 to store a two bedroom.

The staff is very courteous and easy to work with.
Response from the owner: Thanks so much! We loved having you here!
Needed this unit for only a couple of months and got to take advantage of a special offer of buy one month, get one free. What a great deal and the people were super friendly and accommodating. They are in a great location and the property is well laid out, made it easy for my movers to empty my unit. I would absolutely recommend them or use them again!
Response from the owner: We are so glad it worked out for you. It was a pleasure working with you!
The nicest facility clean and extremely competitive pricing, multi location and extremely professional, 30’ trailer and crew cab truck maneuvered through with ease can’t recommend enough staff super friendly and full of options and information
