Fantastic customer service from Leigh today showing me and a friend around the self storage unit which is immaculate and very spacious. We are looking forward to moving in soon. Five stars well deserved.

I'm a delivery driver. I was there because a client rented space for deliveries there. Half an hour before, I had a delivery to another company at a private address. No one was home, and the delivery was unsuccessful. If this client had a contract with this warehouse, the story would be different, and there would be no wait for the goods from us. Renting self-storage space at Attic is a great idea. It saves you time and shows you respect your customers. The staff is very, very helpful; it's like they're your own employees, for a small fee. Thank you, Lee and Kath. I highly recommend it.

I had a great experience at Attic Self Storage thanks to Peter. He was incredibly helpful from the start. Patient, friendly, and took the time to explain everything clearly. I really appreciated how he walked me through the app step by step, making sure I understood how to use it properly. He didn’t rush me at all and was happy to answer all my questions. Excellent customer service, thank you, Peter

We visited Attic self storage to find a storage space that we could use asap. We were met by Leigh and the team who offered us hot tea, coffee or a bottle of water before we discussed our storage requirements. We were given a tour of the location and it was so surprising and reassuring to see clean, well lit and ventilated premises that also offer toilet facilities. Leigh showed us the unit that would meet our needs and we were able to arrange to start our tenancy immediately. I would highly recommend Attic self storage as you get a no nonsense approach with excellent communication, 24 hour access and superb support from day one. Thanks Leigh.
