Very fascinating business model. I fully understand that every choice they made was a product of trying to deliver a good experience at the lowest price possible, in an extremely narrow building.
Given these constraints, I think they did a good job: the common bath was very good and fully equipped with various types of baths (cold, sauna, outdoors). The lounge upstairs was generous with free morning curry, free drink machines and alcohol, and free rice and soup throughout the day.
Two criticisms: one is that the lounge is a bit cramped and is not laid out in a way to facilitate interaction. Everyone is seated in a row, staring at their own screens. (Again, I understand the space constraints involved.) The second is that I don't understand why the lockers are all on their own floor, away from the capsule. The two elevators are already overworked and require long waits; making us take it between room and locker uses up more of our time. (And this isn't a space issue, but a layout issue.)
