Vancouver is pretty nice especially with the new renovations downtown. You can also try places further north such as Battle Ground or Woodburn, WA if you’re into more rural living.
On the Oregon side Hillsboro is in the West and also a nicer area. Many of the people that live there are working in the tech field at companies like Intel. There are many parks that are nice and public amenities. It’s also close to downtown. Only about a 20 to 30 minute drive depending on traffic. Further west from Hillsboro there are two other towns called Forest Grove and Cornelius. These are also fairly nice areas.
I spent time living in the east near Gresham and Troutdale,Vancouver, and Hillsboro. I would say Vancouver and Hillsboro were nicer overall.
