I had heard about capsule hotels from an event attendee years ago and wanted to try out as something different, and different it is.
As my partner pointed out, and because I mentioned it was very plastic-y and therefore very noisy when you get in and out, it kind of looks like a portaloo on its side.
Pros. Super cheap place to stay. Communal kitchen really nice, and has tea and coffee, microwave and big glass fridges. Level 3 had the kitchen, compact lounge/dining area and 16 capsule dorm. I found most guests were considerate of others, keeping noise down etc. suprisingly quite on Fri and Sat nights even though a bar on floor below and Works Square outside. Capsule adequate size, nice cosy duvet and pillow.
Cons
