Hi. Are you ok with the directions given to you so far. If not and if you are new to Doha, follow the cornich road when you come along the road from Sheraton (the pyramid shaped hotel) towards airport. After passing the Movenpic hotel on your right hand side you will come to the museum R/A which I believe under reconstruction. Turn right and follow this road. you will then find a traffic signal light. Just before you reach the lights Al Bustan hotel is on your right hand side. The office you are looking for is on the rear side of this building. Qatari flag is flying at this building.

Good luck
