Very friendly atmosphere in the city, even at night, walking arround, wondering in the streets, looking at sights (good lightning). We went for a wine drinking with few locals to one of the squares, were invited by a man - nightguard of the summer cafe - to sit at "his" cafe, drink wine and chat. Especially helpful, if you speak Russian.

Everything... Kavkaz (Caucasus) mountains, churches, excellent food but you need a car for transport :/ 
And surprisingly quite good beer (Kilikia)
