I stayed here on a work trip, and found Jessica's place to have everything to meet my and my colleagues' needs, including a nice big dining table for co-working and easily accessible internet. It was also very close to the water, with a nice walking path.
As described, there are others on the property in an ADU, though I rarely saw them or the dog (definitely friendly). Depending on what you are in Seattle for, you likely need access to a car to access restaurants, grocery stores, etc.
