Definitely not one of those AirB&Bs that was thrown together for a quick buck, this is a large room (the sleeping area can be curtained off) with separate bathroom in ground floor vaults in one of the courtyard houses that are so typical of the town. The furnishings were clearly assembled with care, the kitchen was so good I was sad not to have used it for anything more than coffee. Francesca is a host who genuinely cares.
Lucera is a tourist-light town with good food & wine: Rough Guide has it as a good first staging post in Puglia heading south, and as usual they weren’t wrong. I didn’t find the castle open, though the walk round the outside was impressive. It’s mostly empty space though I could have enjoyed the ruins of mediaeval state apartments. I gathered the Roman amphitheatre was closed so didn’t bother, the town is nice enough anyway. For an outing let me recommend nearby Troia (possible on the bus, I did it), the duomo is lovely.
If you come by train don’t do what I did and get off at the first Lucera station (they both have the same name), but wait for the 2nd with the proper buildings and the end of the line. Francesca’s place is literally straight on up the hill, straight on still, halfway through town, at the corner of the square. The Gargano railway (and bus) website, and their people, are the place to go for correct info, others (including Foggia FS station departure boards) don’t have the updated full story.
