I think is too much of a hassle, i just keep it simple and stick to 5d4n. Need to save also since i need the money for my booked 8d7n trip to japan this year end. So..is pratunam not near bts?? As someone here said dont stay pratunam...
nearest bts is chitlom , 1.5km walk ...
would advise you to stay silom or sukvhumit area, those hotels near to bts.
For silom, there are few hotels, within 50+ per nite ...
review is ok if u dont hiam ...
Stayed before i residence silom, given upgrade to a bigger room.
price is about $57+ when we booked deluxe with breakfast
Stayed before furama xclusiveSathorn @ $55+ per nite with breakfast
Other nearby hotels include, holiday inn sathorn, heritage (ppl reviewed cockroaches, not advisable to stay), trinity silom ...
From chong nonsi, take bts few stations to siam paragon, bts chitlom, national stadium (mbk) ...
