There will be no problems when you choose to stay here when you are in Hong Kong. They are very friendly, helpful and approachable. The place is very clean, accessible to anywhere and very much safe. Food, convenience stores pharmacies, MTR station, bus stops and a place to get a taxi are just few walks from the place.
Nearest Red line MTR station is Mongkok so I think you'll very much be located at the center of everything in Hong Kong. The famous markets are near, when in doubt where it is just look for Exit D in Mongkok MTR.
Ken's place is such a good choice if you ever visit Hong Kong, so don't hesitate to book from them.
