Hello there!
I don't qualify, i guess, but my wife does 
We are currently not in Serbia, but when we are, we are based in Sremska Mitrovica, some 50 km or 60 minutes drive to the south. However, when we are in Serbia, we are in Novi Sad at least 3 to 4 times a week for one reason or the other. If you want us to get/keep in touch, let me know.
