The hotel has nice features, like the rooftop restaurant and bar, and plenty of space to relax and roam. The room was underwhelming. The intent of design is felt but poorly executed, like the cheap lounging chair, the weird wall-length desk blocking the window, the metal drain that pops up above the shower floor, and the window shade that was ripped to shreds because it doesn't actually fit properly in its guide rails.
