I would definitely recommend Casa Chelsea Damask! Will was a very charming and friendly host. He even came out to meet me in the street because I got lost and he gave me nice cup of tea on arrival (much appreciated because it was a cold day). The bed was very comfortable and warm. Everywhere was very clean, two towels were provided. Nice and quiet, I slept well. The only reason I'm giving him a 9 and not a 10 is because the place seemed a little hard for my taxi driver to find. Will, the host, said I should have given the driver the post-code, but I didn't know to do that (I live in the USA). So if you plan on staying at Casa Chelsea, be sure to communicate clearly with Will about exactly where his flat is and how to get to it! And by the way, the King's Road is a great location - wonderful shops if you take the #11 or #22 bus towards Sloane Square. Will even let me use his bus pass.
