Outstanding! The flat is beautiful, located on a quiet street steps away from everything in Chelsea, and Julia, Jonathan and Mary were wonderful hosts. My husband and I spend 2.5 weeks in this flat and loved it - great layout, lots of space, comfy bed, sunny outdoor patio, well functioning kitchen - everything was top notch. It was our home away from home, but nicer. Whenever we come to London, this will be our first choice of places to stay.
