We chose Allan Fuller after speaking with multiple estate agents in Putney and Barnes. In fact, we chose to not use the sale estate agent that we had used for buying the flat in 2006 and renting it out.
Kate Cooper was an amazing estate agent! She provided a very realistic summary of the London market and understood that we wanted the flat priced to sell. She communicated with us regularly and helped us through the whole sales process over a couple of months - and we were based in the States!
I would have no hesitation in recommending Kate Cooper! (Sorry this review is so late - by 12 months!)
