I am currently a tenant and have been a landlord in the past. I believe we take these types of companies for granted (seeing other reviews on letting agents). Glenda and her whole team make letting properties look easy and their professionalism and integrity is second to none. The house we let has been well maintained and not once have they let us down and they keep their promises everytime.
I cannot imagine that if you choose to let your property/or let through GB that you will be dissapointed. You are in very safe hands.
