Decent stay in this small studio apartment. It met all my needs and expectations for my 2 night stay. There is no kitchenette but there is a fridge and microwave. Yes there are stairs so be aware if you have big bags and aren't able to carry. I had a 45lb suitcase and was fine.
Check in process is a little complicated as it is in a building complex and you need 3 different codes to different doors - I was fine and had no issues. Room looks out onto roof but no one there during my stay, the blinds seem to work pretty well.
Overall, it is a good place to stay if you're using a place to just sleep, shower etc. If you're spending more time in the apt with 2 people it's probably not the best for you. Location is good to get to Downtown/Pike Place but it's a quiet area with few bars/restaurants nearby.
