My wife and I booked this tour at short notice to see something of Qatar whilst on a short stopover. Lika was very prompt with contact and Arshad was an excellent guide.
We opted to tour after dark to avoid the heat of the day which meant the museums were closed, but this would have taken too much time from our 5 hour tour. However, the benefits were less heat, seeing the Falcon market at the Souq, travelling in a Dhow to view the city skyline from the water, visiting the architecture of the Islamic Art Museum and amongst others, visiting The Pearl, a manmade island. After 5 hours with the time approaching 0030, Arshad was still happy and eager to show us more of his city, but our traveller legs were ready for sleep!!
Don't hesitate to take this tour, you'll not be disappointed.
