The fantastic atmosphere, very British, the great location and the superb service made my weekend in London amazing. Everything is located at a walking distance, from Buckingham palace to Westminster or Picadilly, and the nearest underground station (located at 500m) is directly connected to Heathrow airport. We saved a lot of time and worries, and the price was well paid for such a service, included the yummy breakfast. I will definitively come back next time!
