"I would like to thank Humphrey in particular. This was probably the fastest rental experience I had in Sydney. From the inspection at 12 noon to the signing of the contract at 3 pm, it took only three hours. Of course, this was also inseparable from the great assistance of other colleagues in the company. In any case, this was a perfect rental experience. If I were to recommend, I would definitely strongly recommend Humphrey as the first choice. His professionalism and friendliness made everything so easy. "

"It was great to have Humphrey as my leasing executive on my first-time renting experience in Sydney. He is very responsive, friendly, and provides excellent work. My friend and I completed all the procedures within one week with him. zetland
Humphrey was very helpful from the first time showing me the apartment - he made extra time to accomodate for my work schedule.
He also helped with my questions almost immediately and when it came to collecting the keys again offered to meet me between showings to accomodate my crazy schedule.
Made things much easier for me, highly recommend his service."
