Khaosan Road (Thanon Khaosan, ถนนข้าวสาร) is a true backpackers sanctuary with many reasonable priced hotels. Prices between 20 and 50 Euro/dollar are not uncommon. Backpacking doesn’t mean you have to live without the luxuries of life. Some of these hotels even have a swimming pool at the rooftop ! Since Bangkok is ranked among the warmest capitals on earth, this is a welcome amenity to get used to the climate of South East Asia.
