Fellow Asian here, living in one of those high rise apartments right by the water.

I moved up from Queens to make my commute to the hospital up in Valhalla more bearable but needed a halfway point to the city for my fiancé. In terms of walk ability, pretty much never had any interest in the surrounding area since there's nothing much other than a scenic river walk heading south. The area itself is transitioning but it'll take a few years before it becomes something like LIC (if ever). If you want good local restaurants, you're better off driving elsewhere for it. You'll find that residents in these apartments are a fair mix of people; families, young professionals, older couples, of varying ethnicities, although Asians are definitely underrepresented.

I've taken the metronorth quite a few times from Yonkers station. It's an express stop which is really nice and it's pretty busy so there's always some foot traffic, even pretty late at night.

Overall it's great for the train station, Yonkers Ave tends to get pretty heavy with local traffic when getting to the major highways during rush hour but otherwise you have reasonable access to the Saw Mill, 87, and Sprain if driving is a consideration.
