This apartment is right downtown -- a half block from the light-rail station, which we took from the airport and two blocks from Pike's Market. From here, you can walk everywhere downtown. It's an ideal central location.
The apartment itself is beautifully decorated and extremely well equipped. The bathroom is huge and very luxurious. We didn't cook, but the kitchen is gorgeous with lots of counter space and oufitted with high quality dishes, pans and utensils. We appreciated a welcoming bottle of complementary wine.
Two things I would point out: The balcony looks appealing in the photo, but it's not really usable. It overlooks a narrow alley and there really aren't chairs in the unit that fit out there. It's smaller than the photo suggests. Also, while the apartment is advertised as a one-bedroom it is a large studio. The couch makes a very comfortable bed for a third person, but everyone is in one big room.
A nice benefit: The building has a concierge, which allows you to drop off your bags early, or leave them on your departure day if you want to tour and come back for them after check-out time.
Lastly, downtown Seattle is very urban, with plenty of unhoused people, including in the park through which you enter the building. Nobody bothered us and we are used to this in large cities where we've traveled, but those from elsewhere should know what to expect.
