First up, the restaurant and cookery school are separate from the hotel, and contrary to another reviewer's statement, hotel reception told us halfboard is not available. Don't know anything about the cookery school, except that it's not cheap and it's extra. We tried the restaurant once and were not particularly impressed: very poorly heated on a chilly evening in mid-October, the seafood degustazione menu "two starters" was a mistake we were told (a mistake in two languages?), the seafood courses were essentially the same thing three times over - we couldn't have the beef with mushrooms as main, which looking back was a very strange restriction for paying customers. But since one of my pet peeves is people discussing restaurants when the review is supposed to be about a hotel, let's look at the hotel.
No complaints about the accommodation - clean, comfortable, quiet etc, and a great bargain at the rates available from mid-October on. At several km outside Lucca, consider a rented car (the hotel savings will more than pay for the rental over the course of a week). But if you want, while abroad, to watch your own country's TV, forget it - Italian stations only. There's free use of an internet-linked computer just outside the breakfast room, or you can pay extra for wifi.
Breakfast was buffet style, adequate but boring with practically no variation from day to day. Three cereals - corn flakes, bran flakes, choco-rice crispies (if that's what they're called). Fruit drink rather than real fruit juice (not even the From Concentrate stuff which would have been perfectly acceptable), only square slices of processed cheese, coffee from a instant-coffee type machine. A notice said espresso and cappucino was available on request, but the impression gained was that you would be making somewhat of a nuisance of yourself. Fruit was provided (with a stern notice telling you it was for eating at the table and was not to be taken away) but astonishingly it was generally tasteless and unpalatable - you wouldn't want to take it away anyway, after the first time. Not what we expected in Italy, especially with an acclaimed restaurant and cookery school sharing the premises. On the plus side, eggs (but boiled only!) were available, as were thin sliced ham, plain and strawberry yogurt. Even more plus if you like sweet things at breakfast, very good croissants and a variant with sweet custard-like filling, and two varieties of cakes, generally excellent.
