We stayed during the UK 'heatwave' of July 22 and the flat was nice and cool. It is also a good size, meaning having 3 kids in there wasn't an issue. The local area is great, but depending on your mobility the closure of Hammersmith bridge makes taxi's 'home' somewhat expensive. But if you don't mind (the pleasant) 15 mins walk to Hammersmith tube, then this isn't a problem.
