Sukhumvit district is one of Bangkok's busiest parts of the city filled with office buildings, cheap and luxury hotels and virtually any business under the sun that provides foreign expats and tourists on a vacation in Thailand. Sukhumvit's fame requirements are also Nana and Soi Cowboy, which are two of the city's most popular red light areas.
As a popular tourist destination in Bangkok, Sukhumvit is what most tourists do not prefer to stay on a budget. It is true that Sukhumvit has the most moderate and luxuriously priced hotels. But with so many hotels competing for tourists, it's not hard at all to find quality budget hotels on Sukhumvit Road for about Baht 1000 to Baht 1500 per. Night. There are hotels with room rates around the B500, but the quality of such cheap hotels is not so desirable. If you know that you have some degree of comfort to be respected, such as air conditioning, it's best not to choose a hotel in Sukhumvit under the Baht 800.
Sukhumvit Road is a long avenue that extends all the way from central Bangkok and south to Pattaya, a popular beach town. But the best areas for finding cheap hotels on Sukhumvit Road are between Soi 1 through Soi 55 (A Soi in Thai means a side street or lane).
Soi 1 is where Sukhumvit Road begins, and that's also where the Nana Red Light District starts. There are many budget hotels throughout this area as well as 4-star accommodation. Down at Soi 4 Boss Hotel and Heaven @ 4 Hotel, two newly built properties in this area are good examples of budget hotels in the Sukhumvit district. Because both budget hotels are located in the Nana Red Light District, it may not be an ideal family-friendly hotel. Boss Hotel and Heaven @ 4 charge around Baht 1500 per night. I have noticed that newer hotels usually offer promotions for free nights after a minimum period, so it's a good idea to search for new, newly opened hotels in Bangkok.
Further down on Sukhumvit Road near Asoke Junction and adjacent to the Soi Cowboy Red Light District, tourists can also find cheaper accommodation in Bangkok for around Baht 1300 per person. Night. Two good examples are Asoke Suites and Merisess Sukhumvit 16. Both are not the newest or skinnest but not over 4 years, so the conditions for both hotels are still a good choice to live in an active and lively part of Bangkok.
A big advantage of staying close to these hotels is that Sky Trains is driving on elevated trains just across Sukhumvit Road. Sky Train is a popular and efficient mode of transport for getting around in the commercial shopping areas of Bangkok.
