Copenhagen is a city that is almost impossible to dislike. It is big enough to be cosmopolitan, yet small enough to be intimate. Cobbled squares and copper-roofed townhouses are complemented by dazzling modern architecture. It is safe, friendly and clean. Everyone speaks English. Few cities have made life as easy for cyclists. On warm summer days, dozens of people can be seen swimming in the harbor in front of the Opera House. The food is consistently delicious, and around a dozen restaurants can usually boast Michelin stars, including two, noma and Geranium, that are frequently cited as being among the best in the world. Surprisingly, however, Copenhagen has lacked a boutique hotel of real distinction. This changed last November with the opening of the 54-room Hotel Sanders.
