Magnetron, not to go off topic, but where are you seeing public pot smoking?
It is illegal, just as public drinking is, but pot smoking is easier to detect.
Not to mention, if the mayor has his way, smoking tobacco in public, will also be illegal.
EK, take a stroll down 3rd, and you will smell it! 
Lots of places, EK4, most recently on Sunday near the parking lot to the Mt. Si trail on Sunday.
Some other notables: a very busy corner of 3rd and Union last month, six guys in the shallows of the lake at Genesee Park last summer with kids all around, three guys waiting for the bus at Westlake Center, four people at the north end of Pike Place Market last Saturday. It is fairly ubiquitous at places like the Capitol Hill Block Party. The distinctive smell makes it easy to spot. I have only seen it once over here in Stepford.
I don’t venture outside of Ballard much I guess.
Although I did go to a dive in South Seattle last night.
Took me over an hour to get there, but 20 minutes to get home!
I usually am very sensitive to smoke, even someone driving past smoking a cigarette with their window rolled down bothers me.

I was going to take a street tour of those locations to take a look at the buildings, but I can’t do it tonight. Tomorrow!
Hey, we have Green Theory over here in Stepford! (it edged out our favorite Thai place)
The situation is of course constantly evolving - she might be hooking up with another intern to room together - she just got connected with other interns and will explore that idea.
We are talking about a college kid so she would be fine with just a kitchenette in an extended stay place. As long as she has a burner to boil pasta she is happy (according to their site the kitchenette has 2 burners, microwave, and fridge).
In looking online I saw POD apartments in Seattle that were smaller than her freshman dorm! (only a shared kitchen in the building) - that she could not do.
Yes, the apartment on 4th is the Vermont Inn (I peeked out of the bus window to look at it on my way from point A to point B ). The area around it is ok, the best thing is that it os just a block or so from the Seattle Center (Space Needle, Key Arena, EMP). In the summer, it will be a bit noisy because there will be hordes of tourists wandering around all day long. Buses run on 3rd - she can take D line or 2/13 to Queen Anne to get to Safeway to replenish her pasta supply. The rooms most likely will be tiny, but the upside is that it is so close to everything. Since she will not have a car, there are no worries about finding a parking spot for it.
I just came across this (no experience with these guys though) which looks interesting:

I was able to drag my still sore leg around the city to check out the area near the two other places. What saintfan said is spot on. With the exception of Garfield & 5th, one can walk to the downtown center in 20-30 min. Garfield & 5th is in a residential area, closer to the grocery store triad but further away from the fun. 526 Yale Ave N is next to the freeway, so it could be noisy if the unit is facing towards the interstate, but the big advantage that Amazon is right next door. There is the South Lake Union Trolley streetcar that runs nearby:

The Yale Ave neighborhood seemed nice when we saw son last fall close to I5 noise, however. btw- even new high rises do not have air conditioning in Seattle. Note how expensive housing is! Anyone can PM me for info re living in the area from a parent’s point of view.
Ah, Genesee Park; been through there hundreds of times in my youth, although it wasn’t much of a “park” back then but only a weedy field.
But Lake-it was the place to park to go to the hydroplane races, so I’ve been told. Near a grocery store that let you take the carts loaded with cases of beer-back before you had to pay to get in. That’s the story, anyway.
I get that Seattle is an expensive place to live, but it’s all relative. My son is being offered the very same salary as his fellow grads that will be working in Manhattan! http://www.nerdwallet.com/cost-of-living-calculator/compare/seattle-vs-new-york-manhattan
^^The prices quoted for Seattle are generally correct.
I kinda miss being able to sit in the rubber raft to watch the hydro races, just off the south turn.
I realize now it was dangerous as hell, but it was pretty exciting.
Totally forgot that there is a Whole Paycheck store located near Amazon. So occasional pasta replenishment is covered.
I just went up and over the top of Queen Ann yesterday and it is even better than I expected - great neighborhood and there is a Trader Joe’s up there now. I hadn’t been up there in awhile. I would seriously look at that location if she can get to her job ok on transit
QA is likely to be expensive. (They’ve actually had a Trader Joes for at least two decades, long before Ballard- not a lot of singles compared to SLU .)
Here’s the city by zip codes.

She found a place that looks suitable is the point - one of the three options that mom floated is 5th and Garfield
