Katie was a wonderful host: she and Marcus are an extremely welcoming couple, reliable and always available for anything, yet very discreet.
From the very first step in their apartment the feeling of warmth and familiarity really put me at ease and made me feel like I had already been there.
The location of the flat is absolutely invaluable, at the heart of Notting Hill with some unexpected features (e.g. astonishingly beautiful common gardens).
