Cozy in terms of size, but I always felt a bit cold. It didn't help that the Seattle weather had taken a turn, but the unit has a small electric wall heater which struggled to heat the unit, and when it shut off on reaching temp, would cycle back on less than a minute later. Made it tough to get a good night's rest.
There was an issue with the sink backing up with dirty water and foodstuff. Natalie was great about communicating and getting a plumber in, but for a few days there was a rather noxious odor I could smell when I entered.
Otherwise the unit was clean and comfortable. Folks upstairs have a dog who would I could hear running around and barking on occasion, but it wasn't horrendous.
Overall if you need a place convenient to UWashington this would be perfect. I was able to walk to campus in less that 10 mins. Natalie is a great host and communicated often.
