I recently dealt with the fill in manager “John” twice at the Thornleigh Branch, first time I was enquiring about booking temporary storage and he was thorough in explaining and showing me around which was overall a very positive and decent experience he took his time and didn’t rush or pressure me into anything which made the whole overall experience very pleasant, the second time I went to pay and finalise everything not only was he polite, professional and had a certain charm it was definitely very easy and stress free. Overall John has great customer service and good bedside manners and I highly recommend not only storage king but definitely dealing with John, keep up the great work it’s a shame he’s not placed at Thornleigh permanently. Keep up the great work! Signed one very happy customer Corey

Flexible and considerate in their efforts to house my small boat and trailer by ensuring the location was more accessible and well lite at night. The commercial side was a breeze and some issues I had with accessing a portal were quickly and effectively remedied over the desk onsite. All in all, a pleasurable experience with lovely and knowledgeable staff that made it easy.

During my time using Storage King I found all staff very approachable and friendly. Nothing seemed to be to much trouble. Staff seemed very knowledgeable regarding the best storage. During a recent power outage on my moving day Milana and other staff organised to arrive early to allow the gate to be opened manually to let the removalist in. Many thanks Leonie
