Both Boeing facilities are off of I-5, with Everett a good 30 mins north of downtown Seattle and Boeing Field at last 15 mins south of downtown (commute is at least double those times in rush hour).

Cap Hill is right off I-5 and near downtown. Lots of young professionals from Amazon, Meta, Microsoft live there. It has a ton of very good restaurants and pretty much any type of cuisine you could look for. It is a very, very liberal town though and not for everyone. Parish-wise, it’s located near Seattle University which has a nice chapel and obviously a younger community. St. James Cathedral is also in Cap Hill and has a strong community.

Kirkland/Bellevue are east of downtown Seattle and probably add at least 15-20 minutes to the commute vs. somewhere closer to downtown. Both are very nice cities and on the affluent side of things (lots of luxury shopping in Bellevue along with daily sightings of Aston Martin’s and Cybertrucks), so definitely much safer than Seattle. There are a decent amount of young professionals that live there as Microsoft is headquartered nearby and Amazon and Meta have big offices in Bellevue. However, you’ll find more 30-40yos with families, so finding young professionals with a similar situation as your daughter may be more challenging. There are also some really good restaurant options in Kirkland/Bellevue but a lot more spread out than Cap Hill.

Hope your daughter enjoys the outdoors. Lots of places to hike, bike, kayak, paddle board, etc. The weather is pretty perfect from end of May to late Sept, along with really long days (it already stays light out until 8:15). But she’ll want to prepare for some dark days in the winter when she won’t see the sun for a while.
