Hi novita77...

Coming up Salwa Road from Ramada signals turn left at Qatar Deco R/A.

At the next R/A turn left.

Turn second right (at an expanse of wasteland)

I think you drive until you pass the Girls Creativity Centre/Youth Theatre on right side of road and take a right...or you take a right just before it.

Then after you take a right its 100m up on the right hand side.

Hope this helps!
