Budget room rates in hotels and guest houses range 4,2 - 8,4 USD = 150 - 300 THB per night. This price usually includes everything except breakfast, including the internet, but everything must be asked. In Thailand, as in many countries in Asia, you will never know, what is the situation inside the rooms, untill you looked a the room by yourself. Remember that non-smoking is not prohibited in law in Thailand, so check it yourself. Payment is almost always in cash.
