Short update on this...... it is still not completely clear whether this meeting did ACTUALLY happen or not.....

Here's a video uploaded on YT showing some young Italians handing out flyers to some people in front of what appears to me being the Campidoglio but for sure IS NOT the Hotel de Russie:




The meeting apparently took place INSIDE a museum and NOT in the Hotel as reported by a group running a "raid" by storming into the meeting (source: [link to www.net1news.org] )
