"Anyone who’s stayed in the Club Level of an East Asian luxury hotel is familiar with the idea of a “hotel within a hotel,” a section of the hotel that’s as different from the rest of its offerings as first-class flying is from economy. In Tokyo’s Hotel New Otani we’ve found what’s perhaps the most striking example yet: while it’s a perfectly serviceable business hotel, it’s nothing to write home about — unless, of course, you’re talking about the Executive House Zen rooms, which occupy just two floors of the main building, overlooking the grounds of the Akasaka Estate, which is one of the only green spaces in town." - Tablet Hotels
