Copenhagen's Central Hotel & Cafe opened in summer 2013 and was named the world's smallest hotel. The cute one-room hotel has a small cafe, a bathroom with shower, a stereo to connect your iPhone and free WiFi.

Exclusive one-room hotel On the Altar (Op Het Altaar) is located close to Rembrandt Square in the heart of Amsterdam and set in a former Catholic chapel built in 1751. The 350-euro-a-night hotel is shielded from the city noises and tucked away in a small, quiet side street. It was once used as a "shelter church" during the time of persecution of the Catholic people, hence its location. The bedroom doubles up as a living room and is in the main chapel, while the toilet and bathroom is on the second floor. Guests can enjoy modern features, such as a TV and DVD, WiFi and a self-catering kitchen (with free coffee and juice). While it may be one of the world's smallest hotels, the historic chapel has a large luxurious bed with high ceilings creating space.

The silver-leafed front doors lead to a winding staircase taking you up to a coffee area and through to the chapel bedroom with its 15ft-high barrel ceiling and stained glass window with views of the famous Pavilion estate.
