I think you are close but not quite. In the lower left of the border photo there is a roof covering the road. That is Syria border control. You need to go a bit south past that, and then, I suspect, to a building on the other side of the road that has a dome on top. That is likely to be a mosque and it seems to be the kind of place that would host a hospitality center. Also, a welcome center would be located AFTER the customs control, not before.
As for the meeting location, they said HQ so it is most likely in Azaz. It seems to be the living room in someone's house.
If we consider the photo in fromt of the building with the Apple/Leaf and Bunch of Dates artwork, then directly east of it is Bab Al Salameh refugee camp. Given that McCain Foundation is involved in human trafficking that seems significant. I think this is exact enough for location, simply because of the size of the refugee camp. I have also looked at a lot of other locations east of Azaz and they don't seem special in any way.
Not sure we need to find the exact location of the Northern Storm HQ. This must be a fairly well known location given that Azaz was their center of power. So it was likely centrally located too.
If you agree that this refugee camp is what Q was pointing us to, now that we know that SETF and the State Department were in cahoots with McCain in his visit, I think we need to look at SETF activities regarding Syrian refugees, and State as well. Did they organize the invasion of Europe? How many EU refugees came through Bab Al Salameh?
