John Payne (Greenwich branch), led by Nick and Sue, have been brilliant throughout the whole buying process. Actually, they were our vendor's agents, but they were far more helpful than our own estate agent. Nothing was too much trouble for them. They were always on hand to show us round, always willing to solve problems and answer questions and liaise between us and the vendor -- and they were unfailingly friendly and cheerful. They really helped to make a sometimes painful process much easier and less fraught. I couldn't recommend them more highly.
