The customer service standard provided by Chestertons Mayfair far exceeded the service levels of other estate agencies in London. In specific, the agent who supported me, Victor Vuillier, helped me find and arrange viewings for flats listed with Chestertons and other agencies. I really appreciated the time and effort that was dedicated to my housing search. I highly recommend that anyone looking for a flat in London should use Chestertons, in particular the Mayfair branch.
