Has anyone of you travelled in tblisi Georgia? Do you know a cheap but nice place to stay there?please do help. I'm going there in two months.

awesome. Depending on the purpose of your visit and what you'll be getting up to, worth a thought to make use of local security companies. And walk on the safe side of the road, etc.

People can disappear around there, for many reasons. Local journalists have been machine gunned in cafe's for saying the wrong thing. By men in cars suspiciously the same model and layout the FSB uses in Moscow. But it's not a good idea to talk about it, if you're going to be there.
Not exaggerating, it really has been that bad up until very recently, and what guarantee is there that anything's changed?

The chechens still want to keep the oil fields, the ossetians still back whichever side is going to win, the tblisi government still isn't recognized by the kremlin and the abkhazians are still wackados who think it's the height of the cold war. And they're all heavily armed with war materiel.
Oh and the russian frontier bases are still there, not paying rent, and consider themselves sovereign russian territories in georgia with complete lawful autonomy.

Don't forget the black sea fleet launched volleys of 1-ton warheads on the place just a few years ago. A "rogue admiral acting without sanction" the Russians claimed.

On top of all that, they consider themselves far more asiatic (semitic, turk, mountaineers, horsemen and catholics) than russian by heritage. It was once part of the Old Silk trade route (the black sea route, with stopover at Odessa, then on through Iran to the far east).
And on another side of things, during the soviet empire georgia was the primary nuclear research centre. And singly responsible for the production of Russian antitank attack aircraft.

A weird, dangerous, interesting, ancient place of epic proportions.
