Hey crew. Nice work you've done here. Regards the location of the meeting photo, and possibly the doorway photo, like another anon who was posting in the general about this location, I agree that it's at the Bab el Salam at the Turkish / Syria border, just inside the Syria side.
The Floor: Check the floor in the meeting pic and the other pic from a Times article taken at the Bab el Salam crossing. Same flooring.
Northern Storm Brigade set up a press office at Bab el Salam: "Once inside Syrian territory, they are politely ushered into a yellow-brick building, divided by wooden panels into three rooms that serve as the press office for ‘The Northern Storm Brigade,‘a chapter of the FSA which controls the border area, the medieval city of Azaz and territory on the northern outskirts of Aleppo."
