Location location location :) if you want shopping , convenient access to shibuya station, and a block long park at your door, this place is great.
Room size is ridiculously small, but restroom and shower are well appointed. Plan on sliding your luggage under the bed.
We had a blast using the hotel as our base for shopping and restaurants. soak nightclub/ restaurant is on the top floor with great food, music, and views. 5th floor had a lovely restaurant albeit absurdly high priced , coffee shop on lobby level was good as well.
Street access is via a subtly hidden elevator at the corner, so when your taxi drops you off in front of balenciaga or kith, fret not :). Just walk to the corner and look for the sequence hotel sign and elevators :)
