Three bedrooms, living area, kitchen, full bathroom with possibly a half bath if it's a larger place.
Why couldn't a family of 4 be comfortable?
Most families of 4 are living in a 1br if they're lucky. Plenty of families of 10 doing 2brs etc.
Bay Area is seriously a bad choice if you're not in IT or making at least 6 figures combined yearly.
I know folks that make 6 figures yearly and still cannot convince themselves to pay $4000-$5000/month for a 2 bedroom.
