We stayed at the Saint Georges last year. This year we saw they did upgrade the rooms. Nice bathroom, nice room, just a little dark, very difficult to read in bed at night.
The bar & restaurant on the 15th floor is lovely, the buffet breakfast is fine and in the evening it's lovely to eat and look out the windows.
It's a great location because it's 2 streets from Oxford circus and lot's of restaurants and cafe's.
