The LIRR is good yes but there seems to be extremely few apartments available for rent in Nassau County. Or maybe it's just that I always filter by Allows Pets, I'm not sure.
If it were solely up to me I'd be fine living in Bayside/Little Neck, taking the LIRR, for the great Korean and Chinese food and the parks. But my wife prefers to stay where the subway is.
Many parts of LI have few or no apartments, or only 55+ apartments. Great Neck is an exception—-very similar vibes to eastern Queens but no city income tax, better schools, and better cops.
