We really like Juneau and feel it is a great and safe place for our younger children. However living away from extended family is tough especially when considering the cost to fly a family out of town. As our children have grown sometimes it feels like the resources in town are lacking.
To live here you MUST not be afriad of hiking or getting rained on. There are a lot of awesome scenic places to hike to (there are great views on the side of the road too!).
Finding a place to rent is near impossible, especially if you have a pet, and cost significantly more than you'd expect to pay down south.
