London's strict planning laws, whilst keeping a beautiful cityscape, keep the number of high rise hotels to a minimum. Those hotels that have popped up though are blessed with uninterrupted jaw dropping views across the capital. The most impressive of these is the Hilton on Park Lane, where its restaurant, Galvin's, and bar, Windows, are located on the spectacular 28th floor. Be sure to check out the Panoramic Rooms at another luxury hotel nearby too - these rooms at the Sheraton Park Tower offer virtual floor to ceiling, wall to wall windows. The Corinthia hotel is a more traditional hotel, but its location on the river means its river view rooms look over St Paul's cathedral and the city, with its penthouse suites offering some of best private roof terraces in the world.
