According to me ambassador is a very good hotel. I once slept there for one night.
Is situated at a prime spot in the heart of fashionable Sukhumvit Rd., Bangkok's legendary commercial district. Half an hour from Bangkok's Don Muang Internation Airport, close to Queen Sirikit National Convention Centre, and near great shopping and entertainment venues, the Ambassdor is only two minutes walk from Nana Skytrain Station.
