We stayed at Magic's for one night and it was lovely. It's a cute little place about 20 minutes walk from Downtown Seattle. I can't stop gushing about how quaint it was! It was perfect for my friend and I; one bunk per person. Take note that the top bunk is quite close to the ceiling (**this is mentioned in the description; I'm just mentioning this in case one of your party is claustrophobic.)
There were 2 pillows per bed, and they (beds and pillows) were very comfortable. We only had our backpacks, but I think you could comfortably fit 1-2 suitcases against the wall (though that would might decrease your walking space haha).
We didn't cook, but there is a portable stove top in case you might want to. Magic left us snacks, which was a nice little touch :) The shower was easy to use, and Magic left us shower gel, shampoo and towels, so there are some amenities provided. The location was also great as it was about a 20 minute walk to Downtown (or easily accessible with Uber.) Magic was also a friendly host; though we didn't meet in person, he responded quickly, and was respectful and accommodating whenever we communicated.
All in all, I'd say it was perfect for our little weekend :D. I'd definitely recommend it for smaller groups travelling, or for a quick trip to Seattle. Thanks Magic!
