First up i would to apologise i know this is hardly the place i should be asking for advices on italy but hey people here seem really resourceful=),Was wondering what would be the best mode of travell in florence,milano & rome itself and whilst travelling to and fro between these italian cities would a train or plane be a better choice?Also what kind of prices should i expect my accomodations to be?(looking for cheap ones,so long as its not dodgey and clean i am good).Lastly anyone can give me a insight on how much per average a meal would cost over there?
Thanks for reading,i would be very grateful for any answers =)
cheers
