Hi All,
I am back with some nice hotels to recommend.
1 of them is Baiyoke Boutique Hotel. Its a nice, well decorated hotel. Although rooms interior are abit dark due to dark painted walls. But overall, its still a very budget hotel ranging $60+ to $70+ with buffet breakfast. Hourly, there are 10 seaters shuttle van to MBK and Siam Paragon.
If you are looking for non-budget hotel, other than Pathumwan Princess, Novotel Siam Square, Siam @ Siam, you can also consider Holiday Inn Hotel & Resort. It is only a mere 1 minute walk to BTS ChitLom Station. Breakfast is usually not provided, unless you are willing to pay a higher price for it.
