The flat is very close to the Museum of Pop Culture and the Space Needle as well as the pubs and restaurants of Belltown, as well as about a 15--20 min walk from the downtown Westlake light rail station to the airport, so that was super convenient. I even walked from Capital Hill, although it's not super close. There were lots of towels and pillows and the space was very comfortable for two of us, with two bathrooms!
But there was only one key fob for the front door and my roommate had to call the host to get buzzed in to the building. At one point the hose did not pick up or buzz her in and my roommate had to wait on the front step for someone to let her in. This was at night in the dark so it was not safe.
The flat itself is clean and tidy and the kitchen is stocked with dishware if you want to make tea or a snack. It's next to the monorail but there is no sound at night so the flat is very good for sleeping, with comfortable beds. It's very convenient but the front door fob is a problem if there is more than one person staying in the flat.
