I stayed in the Barracks last year December for 3 nights - and I decided to take one of the two less expensive Barroness Suites (at 3500bt/night). Well, it was not really a suite, just a large, nicely decorated room with nice view (especially from the bathroom)... but not really worth the money, I think. You can find really luxurious accomodation somewhere else for that money in Bkk; and I had a look at the "Standard" rooms - really different from the suites, but as well not worth the money, I think. These rooms don't have a bathroom and no minibar, and even not always a tv, i think. Better stay at the Pinnacle.
