odessa is the lovely place. lots of things to see, visit and buy. safe, but beware of gypsies. just look at different direction and avoid eye contact if you see them. they are so-called fortune-tellers but if fact just a skillful theives. a lot of pick-pocketing in crowded places. but you have to visit "7km" market, thats the name of it. great clothes and cheap. i grew up in the neighbouring town, so its easy for me there. you will be safe, just avoid gypsies. also avoid cheap eateries due to high chances of food being not fresh. visit opera theatre, the most beautiful opera theatre in europe. yes, turkish airlines is your best option to get there without stress. dont joke with local authorities. people in odessa has a great sence of humor, but not police and customs. have a lovely trip and enjoy hero- city odessa. you need a camera with big memory card to go there.
