Jumping in here to recommend a week doing inter city travel in Italy with some mates. Did Naples, Rome and Florence last year and it was an absolute cheat code. Cost us 430 quid all in before spending money for 7 nights and we stayed in an unbelievable villa in the Tuscany hills where they made their own wine on the farm and sold you bottles of it for 5 euro! Was also in Naples on the night of Napoli's Serie A title win which is a night I'll never forget. Doing north Italy this May: Milan, Verona, Bologna
