Inn a Day wows with its hyper-cool retro/industrial theme (the hotel is in a former sugar factory) and its location (it towers over the river and Wat Arun). The 11 rooms aren't huge, but they include unique touches such as clear neon shower stalls, while the top-floor suites have two levels and huge claw-foot tubs.
