We had a group of 5 staying for just one night in Seattle, and this apartment was perfect for us! In addition to a really convenient location (very close to the light rail station and just a 20 minute walk from Pike Place), the apartment itself was very clean with charming decorations. The only thing you may want to note is that as other reviews have mentioned, the ceiling height in the hallway leading to the rooms is a little low, so you may have to duck a tiny bit if you're taller. In addition, one of the bedrooms has a pretty low ceiling as well, so it's difficult to stand up straight inside it. All the other rooms are perfectly fine though :)
As a host, John was extremely responsive to any questions we had and super patient when our group had to check in/out a little later than originally planned. We'd definitely recommend this place to anyone looking for a short stay in Seattle!
