if access to the west end is your priority, the green park is the best of the three. leicester square tube is only two stops away which is right in the middle of the theatre district. alternatively, you could travel on foot: the walk is pleasant and not very long. i think the previous postings about the hotel itself are quite thorough.

LH738 and ChrisATL : i checked out of the green park this morning as well! i regret i missed you both (and also sadly missed Barbara at the reception this morning -- she's my favorite).
