I am going to visit to Budapest in the end of August. Since it can not be a direct flight I am looking for flights with only one stop and easy/quick transfer as I will have approximately 60-90 mins. layover depending on the city I land in Europe. The options are Paris, Frankfurt and Munich, I was told Paris is difficult although I do not have own experience. Which one would you recommend me to take? Note that there is only 2-3 flights to Budapest per day since the Hungarian airlines was bankrupted.
