The big 4: bed, shower, Wifi and noise.
1. The bed was very soft and comfortable, I had no trouble sleeping here.
2. The shower was perfect. Great water pressure and no issues with hot water. Heat lamp in the bathroom was nice as well, and they provide quality shampoo and conditioner.
3. The Wi-fi was excellent at about 80mbps down/40mbps up.
4. The noise factor is variable as the walls are quite thin. You can hear chatter here and there throughout the day, and people walking down the hall or going into other units sounds like they're coming into yours at times. That said, at no point in 3 days, including a Friday, was it ever loud at night or disruptive to my sleep. Everyone is very quiet, and from what I've read in other reviews 'thin walls' seems like a thing throughout Seattle, so it's better to be in a building where the neighbors are all actively quiet. If YOU'RE a loud person though, it could be a problem.
Overall this was one of the better airbnbs, esp for the price and location. If you're just looking for a place to crash while in Seattle I highly recommend.
As far as Seattle goes, I really enjoyed the city more than I thought I would. It was a great trip!
Oh, I will say if you have a car it's a bit of a pain as street parking is 4hrs max from 8am-8pm, so there's no sleeping in without risking a ticket, and you have to move your car 3 times a day. I managed to make it ticket free, but cars around mine did not, just be aware. The host can guide you to nearby parking decks for longer term parking if needed.
