Fantastic location. You are only at 20 minutes from center of London (Bus station just next door). Chelsea is a very nice and Cosy location. Darya was an excellent host. The apartment is spacious and fits perfectly 4 persons. The apartment is not Air conditioned. Whist the occupants of the basement are preserved, it could be an issue for the ones staying on the ground floor especially during heated days.
I would definitely recommend Darya
