5 of my friends and I stayed in Brittni's place for 1 weekend and absolutely loved it! The apartment is very clean and stylish and has all the amenities one would need on a trip like soap, clean towels, coffee maker, etc... Though we were a bit squished for space with the 6 of us, I would consider that more of a 'us' problem and not the host's as we didn't feel there was any discrepancy with what was listed on the website and still really enjoyed our stay. That being said, I would say 5 people is the max amount of people who could stay here comfortably with no problems as the pull out couch bed is a bit small to share with another person but still doable.
Brittni was a great host, fast with communication and also provided a nice binder that had a bunch of recommendations with places to visit. The location is also nice and Brittni provided us with a parking pass so we didn't have to pay extra/worry about where to park the car.
All in all it is very east to recommend this cozy apartment as a place to stay in Seattle and I definitely would consider staying here again the next time I go to Seattle
