I will be visiting Kosice in the fall and would like to go to Krakow for two nights and then return to Kosice for my final day in Slovakia. The train takes too long and airfare is too expensive. I found "EuroBus" on the internet and they transport from Kosice Airport to Krakow Airport in four hours and also provide transportaion from Krakow AP to Kosice AP. This would be the perfect solution to my dilemma. Any reviews on this service would be appreciated. Also if anyone can recommend a tour company for the Aushwitz-Berkinau tour and I would appreciate that also.
