From the outside, it looks like a 1920s residential building—it’s so low key that you might even miss the entrance at first. But once you walk in, it’s a completely different world: bold colors, contemporary artworks and über-chic décor make up the boutique hotel JIA Shanghai. The hotel has just 55 rooms (with two penthouses), all with stylish designs that make you feel as if you’ve stepped into a magazine spread.
