I'm Rosie's husband Chris and I stayed for one night while attending an awards dinner down the road. It was a great choice, as despite being in the heart of London it's very quiet, and in a leafy, gated apartment complex just 5 mins walk from Marble Arch tube station. The apartment's small, but clean and smart and as its on the top (5th) floor it was lovely to sit outside on the balcony in the evening and enjoy the late sunshine. Chris was an excellent host and I would be very happy to stay again if the opportunity arises.
