I loved the decor at Kex and the atmosphere in the bar downstairs. The decor is very hipster, but in a very cozy, authentic way. We had a great time in the bar downstairs during Airwaves with Seattle radio station KEXP.
A few nights later we stayed there and again- super impressed by the decor. The rooms were pretty standard.
The only suggestion I have is that using the school style metal lockers is super loud. We had an early flight to catch and there was no way to be quiet with the metal lockers. Also, the guy who checked us in at the front desk was nice but definitely didn't go out of his way to be particularly informative or helpful. Other than that everything went well.
