Bangkok has a great range of accommodation, with a budget to suit all travelers. You'll find some of the world's best, and worst hotels in Bangkok. Roughly speaking:
You should choose the region in which you stay carefully. Bangkok is a big city and being in the right place will save you time and money in transport costs, and ensure you get a good nights sleep. See the guide on where to stay in Bangkok.
Boutique hotels have become very popular in Bangkok in recent years. They normally have 10 rooms or less, and offer a more personal service. There is a great range of boutique hotels in Old Bangkok (Rattanakosin Island) and Sukhumvit Road area.
The guest fee is a Bangkok hotel phenomenon. A charge of around 500 baht is added to your bill if you bring along a guest to your room. Very few hotels, even the most exclusive, will refuse you to bring a guest to your room. But, the fee is obviously aimed at controlling local sex workers.
Of course Bangkok has a healthy choice of hotels, for all budgets, but here are other accommodation options too. There are a number of hostels in the city, providing cheap accommodation and an opportunity to meet fellow travelers. There are also a number of local families who have rooms to rent. These are often called home-stays, and although found in Bangkok, are less common than in more rural areas. Home-stays are good if you want a taste of Bangkok more from a locals perspective. And they are generally very cheap, so good for long stays in the city.
Bangkok is the capital city of Thailand, and definitely worth a stop to any trip to Thailand.
