The city of Amsterdam does a great job of blending the old with the new — so it's no surprise it's home to a hotel that does the same. Designed by Piero Lissoni, the Conservatorium Hotel Amsterdam is based around a 19th century building that was once home to the Sweelinck Music Conservatorium, which has been combined with a huge glass-covered atrium to create a space all its own. Inside, you'll find 129 rooms featuring modern furniture, free Wi-Fi, and upscale bathrooms with TVs in the mirrors, as well as a lounge, cafe, restaurant, and bar. Outside, the P.C. Hoofstraat and the city's best museums are just steps away.
