I can vouch for Jimmy also.Have used his service via Dragoncastle and he is particularly helpful and knowledgeable with general tourist enquiries.As mentioned previously Pinnacle is good value and well located if Babylon and nearby Silom is your type of action.I think Thai Guy raised the issue of their superior breakfast to Tarntawan and I agree it has better variety for Asian as well as the standard buffet style breakfast.

If you are a regular visitor to Bangkok try all the hotels mentioned on the board;all of them are interesting in their own way.
