Sandra is an excellent host. She keeps a beautiful house with lot's a lovely touches, including a fridge stocked with breakfast goodies. One of the best showers we've ever had!! :-) We stayed in the smaller room, which was perfect for us but were lucky enough to be shown the larger apartment before we left - stunning! The house is easy walking distance from Kew station (around 5 mins), and has everything you need within a few minutes walk including a large M&S (great to stock up on grub), Boots and even a Costa! Various clothing outlets are also available. There is also a rather excellent kebab/chippy by the station. If you are a walker like us, the Thames path is only 10 minutes walk away.
Be aware: If you a coming to this part of London, you will get a lot of planes overhead - wherever you stay - but they seem to die down over night, and as we spent three days in this area we got used to it. Overall: thoroughly recommended and you wont find a better host.
