Riverside Capsule Hotel - Tokyo, Japan
As its name implies, the Riverside Capsule Hotel in Tokyo isn't known for its spacious accommodations. In fact, staying at the hotel is kind of like sleeping in a bunk bed that looks like the inside of a microwave oven. As long as you're not claustrophobic, it can be surprisingly cozy.
Some may find the sleeping quarters not all they're stacked up to be. The small spaces include TVs, alarm clocks, mattresses and pillows, and that's about it. The capsules are so tiny, your luggage has to be stashed in a locker during your stay. Also, don't expect to use the limited space to snuggle up to your sweetie, as the floors are strictly separated by gender, even for married couples. The division of the sexes makes the restroom situation a bit more bearable, as the facilities are all communal.
Still, you get what you pay for, and spaces at the Riverside Capsule Hotel are cheap. As of 2011, capsules are still less than $35 per night, which isn't bad for a safe, clean place to snooze in the Land of the Rising Sun.
