Trong was an excellent host who was in constant contact before check in, and once we checked in he left us with instructions for things around his apartment, and a full list of restaurants and various attractions around the city.
He provided clean towels, a comfy aero-bed for the two of us along with the regular bed, a place to hang up clothes, and there was even an iron and steamer that he let me use. We had four people and his space was huge, we never felt cramped.
The place was walking distance to many attractions nearby, including Pikes Place, the underground tour, waterfront, and pioneer square. We even made it out walking to the space needle one day, which surprised us, but you can get there by cab very cheaply. If you want to make it to a sporting event, the stadiums are literally across the street. There were two games while we were there and were not bothered, if you aren't interested in sports.
