Me and my husband Mike have just had the very best experience with this company. Ryan has great communication, is friendly and efficient. The storage facility is so clean, well organised and available to you whenever you need it. The price was extremely reasonable and we would recommend them 1000%. Such good value for excellent service. Thank you Mammoth.
Wonderful service. I've rented an outdoor container and an indoor locker. Ryan showed me the storage, explained the charges and advised about padlocks. Other staff were friendly and helpful too. Cost effective and convenient. I would highly recommend.

Very reasonably priced storage, the unit was newly built, secure and clean. 24 hour access and extremely helpful staff. Only minor criticism is that car access is tight if someone's accessing a container.

Used a storage box for a year. Nicely laid out place with easy access for out of hours usage.

This is a classic case of "don't judge a book by its cover"! I have used a few other storage places in the past; Mammoth's interior looks and feels much better, more secure, coupled with very helpful interactions with staff (must mention Max and Ryan). I shall definitely use this facility again and would recommend others to take the opportunity to see Mammoth from the inside. Hence, my 5 star rating without any hesitation.
