The name says it all: from the moment you walk into the lobby you’re bathed in an ambient indigo light. It feels like it belongs more in Tokyo’s Shinjuku than in Brooklyn’s Park Slope. The guest rooms are neatly packaged with gleaming white furnishings that complement to blue theme to produce a futuristic sci-fi vibe. But if you book a room with a Manhattan view (and you should), you’ll only have to look out over the industrial riverside landscape at the skyline to restore a sense of here-and-now. Though the aesthetic may be fanciful, the Blue’s best virtues are practical: reasonable rates within an easy cab ride of Lower Manhattan and an easy walk of Fifth Avenue restaurants.
