We had limited time in Washington DC so we pre-booked this tour through Tripadvisor, we chose this specific tour purely due to it fitting with our itinerary. We had to make our way to the Hyatt hotel for the pick up. The only issue we had is that the tour guide tried to message us (whatsapp) on the morning of the tour to confirm the pick up and to give more specific information about the pick up - but coming form the UK we did not have a working mobile so we only got the message later - however we met the tour guide easily enough. The tour itself was great both the driver and the tour guide were very friendly and knowledgeable, they gave us a lot of information as we drove around. The pace of the tour was very relaxed and we were allowed sufficient time at each location - we never felt rushed and never felt like we had too much time anywhere. They took us to most of the main attractions including some that were not mentioned on the itinerary, and in doing so gave us a good orientation of Washington DC.
