Siham is an excellent guide.  His knowledge of Doha and Qatar is excellent along with his mastery of the English language.

Areas for improvement to really make his services the absolute best in Qatar are the following:

1.  Describe any add-ons in detail to the itinerary and the time it will take for them.

2.  Talk a little less.

3.  Be a little less aggressive with his driving.

Siham was my guide for a custom private tour over two days. He is friendly, knowledgeable, and dependable. He made the history and current events in Qatar come to life. I knew nothing of the country when I planned my stopover, and left with a deep respect for Qatar. He took me to a couple places I would not have been able to find on my own. I really appreciate his help and give him the highest recommendation to anyone looking for a guide in Qatar. I'm already planning to return. 

Siham was very good guide. At the beginning it was easy to agree with him and he was punctual. We had very interesting tour, he gave lot of info, saw a lot and all the time it was pleasant and relaxed. I would recommend him.
