There is a phone button marked "Whatever! Whenever!" in the room: this best describes the experience we had. Top-notch service, excellent breakfast and the fantastic "Conservartory Suite" made this a high-class stay in London. All is very british, especially the Afternoon Tea (really, try it!). Fine room perfumes, king size bed, 24h service and a fantastic view through the glass roof. One of the best five hotels we have been so far!
