This place is definitely compact, but in the most efficient way possible. My boyfriend and I stayed here for 4 days, and it was perfect for our trip. We didn't spend a lot of time in the room during the days - we packed a ton of site-seeing into our full days. Magic's place was perfect for us to Uber or walk back to from downtown (about a 10 minute walk), and we mainly needed it to be our crashing place every night.
We ended up sleeping on the futon (bottom bunk) because the top was a little close to the ceiling - the mattress was comfy enough for us both. The walls are a little bit thin - as expected in a building like that. Magic provided a fan, which was enough white noise at night to block out any noise in within the building.
Other than that, check in and out was super easy and painless. Magic was very quick to respond back to any messages we sent his way. We had an absolutely great time staying in Seattle!
