This alien tower is Amsterdam’s newest luxury hotel. Although it may be a bit of an eyesore to more traditional travelers, the 120-room Fletcher Hotel is one-of-a-kind when it comes to pulling off this type of hospitable futuristic aesthetic in such a grand scale. Whether you fancy its hyper-modern design or would rather stay at a warm cottage downtown, this building is an architectural marvel in its own right. The Fletcher was designed by the world-renowned architect Benthem Crouwel with eco chic interiors designed by Dutch artist Robert Kolenik. Catch some spectacular panoramic views of Amsterdam from the appropriately titled Skyrestaurant and lounge.
