Ewww. I used to live in Mongkok but this year I came back for vacation and I'm currently staying in my own apartment in Tuen Mun. Frankly I don't like it here; it's not as convenient as Mongkok, where all the shopping malls and restaurants are right at the base of your apartment.
when i am on vacation i stay with my por por in Sheng shui and sometimes hop around yuen long or central (got aunt and uncle living there). Prefer Central!!
Im staying in yaumatei when im there on holiday. I love the yau-tsim-mong district!!!!!!!!!!!!!!!!!!!!!!!!!
