We had a great stay at Rachel's.
She and her family are really lovely, caring hosts. The house is beautiful and spacious. We were a group of 8 and felt pretty much at home, the hosts were out of town but we met them and had really good communication via Chat. The house would have had enough space for even more of us. :) putney is a lovely neighbourhod, it takes ca 1 hour to commute into the centre via public transport. Great value for money, absolute recommendation!
