I am recommending Jamesdean in Horley with an excellent rating. As a landlord with multiple buy-to-let properties I now use them as my sole agent. They provide a friendly & personal service, and seek the appropriate tenant for each flat/house to ensure a long let not multiple changeovers.
They provide a full management service to resolve any repairs or problems promptly in my absence, and deal with everything in branch, unlike larger agencies who pass you from department to department. Although I do not provide furnished flats they took the trouble to source a bed for a couples requirements.
They offer a very efficient service & my properties are never empty for long at the end of each tenancy.
