Arpan Kumar · 7 months agoDinh, our agent, she has been best through out our agreement with the property. She was always respectful and would try her best to take care of any requests made. She is very thorough in her inspections before and after the tenancy, which makes her a better agent. Highly recommend agency. Cheers,
Vishal Jevtani · a year agoWhitestone were lovely to me as a tenant. On my first day at the apartment they met me onsite with the keys and carried my suitcases up the stairs. Throughout the tenancy their communication was great and they were pro-active in sending a renewed lease. I really appreciated my time with them.
