I have to say that the Holiday Inn Express was a great value London hotel, which was super for our family of four. The room was en suite and had a large and powerful shower, which fitted 3 of us no problem. There were extra towels and it was really clean and tidy.
Breakfast was a self service buffet, with scrambled eggs and sausages, in addition to the standard cereal, pastries, yogurt, cheese etc and the boys really enjoyed it.
West Kensington tube was less than a 5 minute walk away and Earls Court one not much further.
