Like most Asian capitals, Bangkok is a city that never sleeps. The capital of the ancient kingdom of Siam is divided into halves by a railroad track. On the one side you will find Old Bangkok surrounded by the river Mae Nam Chao Praya, a district of temples and markets. On the other side is the very modern concrete city, lined with shopping malls and financial districts. The architecture of the city varies throughout the different neighbourhoods where you may find yourself, if you're looking for a hotel in Bangkok; it's in your best interest to inquire upstream, depending on the type of accommodation you're looking for. The central neighbourhoods Silom and Siam Square in the centre offer upscale hotels. There is an excellent quality of service. The business districts of Bangra, Sathorn and Yannawa, in the north of the city also offer a luxury hotel. Places that are slightly hectic during the day tend to become very calm once night falls.
