CK's flat was a clean cozy flat that was centrally located and close to the MTR. Although CK was unable to meet us in person, he provided excellent and thorough instructions to guide us around his flat. 4 people was a tight squeeze (especially if you take into account luggage), but I do think CK's flat can comfortably accommodate 2-3 people easily. Would recommend for non-Cantonese/Mandarin speakers to have on hand the flat's address written in Chinese if you are using taxis to get around.
