I may be moving to Seattle from Ireland. I'm 23, and don't plan on raising a family for at least another 600 years. Which part should I move to?
Honestly, that depends on quite a bit: what are you into, do you plan to have a car, do you think you’re likely to get a job/go to school in a central, public transit-accessible area, are you willing to have roommates/can you afford a pricey rent by yourself?
That said, there are a couple of neighborhoods I’d recommend, all of which are fairly convenient to live in car-free. Capitol Hill is a pretty vibrant part of town, is very queer-friendly, and actually has some restaurants and social activities that are open past 9pm. Belltown is a little older and a little more run-down, but is amazingly charming. And the University District isn’t quite as hopping as Capitol Hill, but has a lot more roommate options (including some large shared houses) and a younger social scene, plus, if you live near The Ave (aka University Avenue), has more walkable (often cheap) restaurant and bar options.
When/if you are ready to start looking for a place to live, you could do much worse than to check out Craigslist for apartment/roommate listings. Your best bet for getting a feel for the scene in the neighborhoods I mention is to start reading The Stranger online.
Good luck! If you haven’t been to Seattle yet, you’ll probably find the climate pretty familiar. I don’t know if you’re an American living abroad or an Irishman seeking to move here, so I don’t know what advice to give you. There isn’t exactly a distinct Irish community here, but there are a lot of Irish expatriates in the area and (if you are Irish) you may be able to find someone who can help you make the transition.
