Cannot recommend Kate's flat highly enough. Really excellent. Stayed for 10 days. It was (for me) the perfect location. Off a relatively busy high street in a gated area, but extremely quiet. Very close (7 minutes walk) to major a London Underground station (Hammersmith - access to four lines) and London Bus hub. Plenty of the good and varied dining options close by and good supermarket access. Couldn't ask for a better location, at great value.
The flat itself was excellent. Cozy, probably ideal for a solo traveller or a couple, but there is a good sofa bed available just in case. Modern appliances, all in excellent working order. Very comfortable bed. As I said, it is on a major high street, but you would not know it from the lack of noise.
Kate and her team were a pleasure to interact with. Extremely responsive, flexible and polite. Provided detailed instructions/information regarding the flat itself and the surrounding area. Made sure the flat was well stocked with towels and little things like scissors in the kitchen drawer and a pencil (it's the attention to detail).
I am originally from London and come back every year. In the future, I will always check to see if Kate's flat is available. Highly recommend. A+.
