2. The One Hotel in Angkor, Cambodia

Perched on top of a bistro in a French colonial townhouse, the One Hotel comes fully equipped with a modernist sleigh bed fit for a snow queen, a gorgeous Jacuzzi, iPod and mobile phone, and rooftop terrace. There's also an outdoor shower and stylish terrazzo bathroom overlooking the lovely back garden. Double-glazing prevents the outdoor world intruding on guests' slumbers in this hip, bohemian part of Angkor. The bistro's chef delights guests with his inspired take on traditional Cambodian cuisine and the staff all belong to the local training institute for Cambodian youth; an unusual but worthwhile set-up for hotels with only one room, isn't it?
