I have an opportunity to visit one of these cities for 3 days in mid October. Never been there before. I will be an independent traveller. I am in my 20's. I know they are all very inexpensive which is something I really like. I don't like going to places where there are lot of tourists and enjoy going to off the beaten path places. I guess the food would be better in Krakow. I hear Krakow is beautiful but I have always wanted to see Ukraine. I hear the nightlife in Kiev is great so I am not sure which to choose. Any advice would be great. Don't know much about Lviv but researching it seems really cool too.
