Very central location. Quiet but right in heart of shopping and by Hyde Park. Large rooms for London. Well maintained. Staff were professional and polite.

We had a room, 1329, with a view of Parliament, Big Ben and the London Eye! Located immediately across Westminster Bridge in the south bank of the Thames, convenient to the Waterloo or Westminster Tube Stations, anywhere you wanted to go was minutes away! Room service 24/7 was wonderful and the menu had many choices. But we hit 4 different Pubs,a MUST, when we were there for the week! The staff was so helpful and polite. The people of London are so good at politeness! Each night, the Eye lights up differently giving us a beautiful light show each night!
