I suggest the Sheraton Royal Orchid on the river. It is beautiful and all rooms have a river view. It should cost no more than about $ 100. per night. Visit www.diethelm-travel.com They are the biggest travel agency in Thailand and you can book your hotels through them. I have personal experience and can tell you that they are very reliable. Thier hotel prices for all of Thailand are absolutely the cheapest. Have a great time!
