As you can tell... Sooo many yummy choices!
What are you looking for? What is most important to you? Walking score, school district, commute to work...
If you can answer those questions, you will find what you need.
To help answer some of your questions, One of my favorite websites for newbies, or even your average local is www.portlandneighborhood.com
This website has great local information all about Portland Neighborhoods.
Ultimately, the decision is yours! You just need to ask yourself what is most important to you and weigh your options and then decide.
Best of luck!
