Tomorrow, a 32 room-hotel opens in London's Heathrow airport, offering free Wi-Fi and other perks. Yotel rates start at $50 for four hours (but more typically about $110). Inspired by the smart way first-class airline seats use space, Yotel offers a pod that measures between 75 and 107 square feet. Each pod has a double bed, bathroom with shower, pull-down desk, flat-screen TV—plus free Wi-Fi. Earlier this summer, Yotel opened a hotel in Gatwick airport. At last, the word is getting out that budget travelers like a bit of style.
