Party vacationers in search of an affordable place to stay in any of Bangkok's nightlife districts will have no problems at all finding guest friendly hotels with clean modern rooms. With so many new hotels plus older and well kept properties in Bangkok to choose from, making a decision on where to spend the hard earned cash on a room can inundate the best savvy budget traveler.
To begin the search and make your hotel research easier start by looking around the city's nightlife entertainment districts for guest friendly hotels that you can afford. Many budget hotels in the $40 to $50 USD range are found right in Nana, Patpong and Soi Cowboy, which are Bangkok's 3 main nightlife hubs. Staying at a hotel near any of the 3 nightlife districts in Bangkok will save budget travelers time and a bit of money on having to pay for taxis and train fares even though those modes of transportation are relatively inexpensive.
That said, if given the choice, it is best to stay near the nightlife district in Nana. As a central location in the Sukhumvit district, Nana has everything party seekers need for a great night out in Bangkok. There are plenty of places to eat, shop and of course drink and party. Since the area mainly caters to foreigners many of the businesses in Nana are able to help foreigners with basic English.
And Nana has the most budget quality hotels as well, most of them are located right through Sukhumvit 4, just past the go go bar center of Nana Entertainment Plaza.
The first highly recommended hotel in Nana on Sukhumvit 4 is the Boss Suites. This is a new hotel opened in early 2010. The rooms there are modern with a comfortable room size plus the friendliest guest services I've experienced in a hotel with a $45 USD per night price tag. Not bad at all since the hotel offers guests use of a swimming pool and a little gym above it.
Across is the Woraburi Sukhumvit Hotel and Resort. Though an older hotel property it is well kept and as the name implies you do get a resort like feel in a concrete jungle such as Bangkok. Rooms at the Woraburi especially the standard rooms are very basic yet clean though small. But you can't complain since it only cost around $25 USD per night.
Just a bit further away on Sukhumvit 4 and closer to Nana Entertainment Plaza is the newer Heaven@4 and older Royal Ivory Hotel. Both hotels are very good options though the Royal Ivory Hotel is the better choice since the rooms are bigger and there is a swimming pool.
The last recommended Bangkok guest friendly hotels is the Manhattan Hotel. Located on the edge of Nana nightlife, however there are many clubs and popular bars surrounding the Manhattan Hotel. It's a huge hotel property and very popular since the rooms can go as low as $40 USD during low season rooms sales.
