The apartment is just brilliant. We (2 colleagues) used the apartment for a business trip, and the apartment did everything we needed. Huge amounts of space, both private bedroom space, and shared social space. The kitchen was well equipped including basic store cupboard things which was great. TV's had access to netflix etc if that's your thing. The apartment was quiet, we were not aware of any neighbors around us, and street noise was minimal.
The location was as we expected, down by the water, with great views. There is an elevator just outside the building that saves a walk up the steps, but be warned, there are hills if you are heading up to downtown. If it snows, as we experienced, the location can be tricky to navigate. but that's not a negative of the apartment, Seattle as a whole can't deal with snow! The old freeway which runs behind the building is now closed, so do not be concerned if you see that on a map and you are choosing somewhere to stay. Within 5 minutes walk you will find convenience stores, many places to eat and drink, as well as the Pike Place Market complex.
Elsie the host was super easy to communicate with, and helpful with simple local tips when we needed them. As far as hosts go, I have not experienced that level of customer care before - thank you.
