The rise of "capsule hotels"

Yotel has operated its pod hotels in London’s Heathrow and Gatwick airports since 2007, and in Amsterdam’s Schiphol since 2008.

Described by the company as being “inspired by first-class airline cabins,” and by one user review as “a cross between a train compartment and a space ship,” these small units pack in single or double beds, entertainment systems, a work desk and an en suite bathroom into between 7 to 10 square meters.

The cabins –32 at Heathrow, 46 at Gatwick and 57 at Schiphol — cost about £25 ($39) for four hours, or about £60 ($93) overnight.

Yotel also operates a hotel based on a similar concept in New York City, with 669 slightly larger rooms.
