Amari Watergate is located at pratumwan. jus in the heart of shopping areas! walking distance to Central shopping centre, four-faced buddha and the famous wanton mee!!! =) yum.
try out Dream Hotel at Sukhumvit Soi 11 or 13 or sth don't rmb which. perfect staff. or go for centrepoint petchburi, opposite platinum mall. hope thailand finds peace soon.
I stayed in baiyoke hotel the previous time i went. nice environment and food. though the services are a little slow. but overall experience was great! :)
