The location of Yins apartment is the best. It's very central, right down the street from the escalators and right in the middle of the action. The apartment is spotless and the bed is actually soft (which never happens in Asia). I slept great, it's pretty quiet for being right on the main drag.
Yin was actually around during my stay and was open to showing me a few places around her area.
Staying with Yin was a great choice.
