We had a lovely stay while visiting Seattle for the first time. Overall, the home was in a great location, quiet, and clean. Michael was very helpful leading up to our stay, answering questions along the way. The apartment had a nice, airy and bright feel, the terrace was cute and the proximity to good restaurants and bars within 10 minute walking distance was pleasant.
There was a strange smell when we first walked in that eventually dissipated but it was a bit uncomfortable to come into the apartment with that smell. We later discovered that t seems to be a smell found throughout grungy Seattle, ha! The sound from the upstairs guests didn't bother us, they were pretty respectful but the walls are thin and you will hear people walking/talking.
The bed is firm, so if you don't like a firmer bed, maybe look elsewhere.
This wasn't listed in the description, but the bathroom is right next to the kitchen and the kitchen window doesn't have a curtain or blind, so be mindful that your neighbors may see you in your skivvies if you're not aware :)
