Catherines's house is very neat and located in a quiet and beautiful neighbourhood with convenient access to all kinds of amenities. Bus/tube stations, river pathways, supermarkets and restaurants are within walking distance. You won't spend much time on the traffic if your workplace/school is based in west London.
Catherine and her family (including two lovely cats!) are very friendly hosts. The room she provided is very clean, tidy and spacious. She also shared the washing machine and the well-equipped kitchen with me. I enjoyed my stay here.
