Overall we had a great experience. Tommy was so friendly and accommodating to everything, especially the early check-in (we did a road trip from LA to Seattle, and checking in at 2PM rather than 3PM was amazing and much needed after such a long drive).
The rail being so close was GREAT, but there are no restaurants nearby in case you did have to eat closer to the airbnb. There are 2 safeways nearby to grab groceries, but they aren't in the most glamorous parts of town - so keep all that in mind when planning your daily schedules.
Saw other reviews mentioned the noisy street - which is accurate. However it was not miserable for us as we're used to noisy LA, ha!
The place is 3 stories, so keep that in mind too as you have to bring your suitcases all the way up! It's a tall and skinny house so the stairs are pretty narrow.
Lastly, the beds were SO comfy and the place was extremely clean which was awesome and nice to come 'home' to after hours of being downtown.
