Bellevue is a lovely suburban place to raise children. I came here as a little kid in 1967. I am a product of Bellevue schools who went to an Ivy League school, on for a Masters and a PhD. Schools here are competitive, especially in west Bellevue.
Bellevue is growing rapidly. The down town area is sprouting nice condos on a weekly basis, it seems. Shopping is plentiful, as are parks, movie theaters, and restaurants. There are at least three farmer's markets in Bellevue, so Tuesdays, Thursdays or Saturdays you can find fresh produce, beautiful flowers or home made bakery goods, fresh fish, meats and cheeses fresh from the area. Also there is a Whole Foods market walking distance from the down town center. Medical care is excellent and very near by, less than a mile from the center of Bellevue are two large and well regarded hospitals and myriad clinics and doctor's and dentist's offices.
Traffic is awful, however. It is frustrating to try to cross Bellevue east to west or west to east. The north/south roads are better. The people are not overwhelmingly friendly or easy to get to know, but churches and clubs provide venues for making new friends. Volunteerism is encouraged in the schools too. People generally keep their property up nicely, contribute to local causes and watch out for each other's children. It is 45 minutes from skiing in the winter and fifteen minutes from sailing in the summer. But getting back on a Sunday afternoon is a nightmare.
