This is exactly as it looks: a bunk bed in a hotel. I never really felt unsafe considering a required key card to get into not only the hotel itself, but also the bunk room. There isn't a microwave or stove for cooking so you're required to eat cold or order out. The staff are super helpful and friendly.
There's also three bathrooms for just the bunk room which is nice, but they are shared amongst all of the bunk room attendees so you can't leave your things around. They also don't provide locks, so if you're traveling with a suitcase or two bring at least two locks. I never found people going through my stuff and all of the residents I met were nice, but always be cautious!
The hotel isn't on the greatest side of town, but it's wonderful for food, travel, and generally getting around. Shops, MAX stops, and restaurants are close by.
Overall great stay and very nice place to visit for 2-3 days.
