Pricilla and Simon are A* hosts. Their flat is really lovely and homely, and in an excellent location of you're looking for a place in West London. For us, driving in from the M4, it was perfect as we were able to park free of charge on their street and travel in to town.
They gave us some excellent recommendations to have dinner locally, and helped us plan our trip to the British Museum. We would happily stay again, and hope to next time we come to London.
