I have only been to Armenia and it was really fun.
I went there in the winter, but I've been told that it gets unbearably hot in the summer (especially Yerevan), while autumn is the best season to visit. Very fun if you enjoy exploring around ancient monasteries hidden in gorgeous mountain valleys kind of in the middle of nowhere (Geghard, Khor Virap, Noravank, Sevanavank, you can find a lot of lists of online). I also really enjoyed visiting the Byurakan astrophysical observatory as well as the holy city of Echmiadzin, there's a restaurant which used to be a medieval refectory, very cool and great food. Yerevan is pretty interesting too, there are a few nice landmarks and museums to see but I wouldn't spend more than 2-3 days at most just visiting the city itself, the countryside has much more to offer, especially if you like hiking. As far as I know, the Armenia - Turkey border is closed. I'm not sure if you're gf will be allowed into the country if she has a Turkish passport.
