Excellent communication (this was our first AirBnB-experience and Sandra was very helpful when I was fumbling withe the booking. And both she and husband Neil were helpful during our stay.)
The place was clean and tidy and there was coffee, tea, bread etc. Nice after a long journey.
And yes, Catford is far from Picadilly, but it is simple and fast to reach by train. Simpler, faster, and less smelly than many trips you make on the tube.
Seven stars out of six.
