 Nothing really I didn t like the look of the breakfast canteen much as it s a buffet with loads of queues The hotel is absolutely massive hence tons of people so I went to Claridge s for breakfast 
 I got a free upgraded room and free wifi in my room so good service Parking convenient below hotel and on site large room comfy soundproofed too Great location 10 mins walk from Marble Arch and just across the street from the tube
