Vacation rentals -- apartments either down by the port or in the paese of Capraia Isola -- are more common than traditional hotels (of which there are only two on Capraia). A minimum stay of a week is normally required. Agenzia Parco (tel. 0586/905071; www.isoladicapraia.it) and Agenzia della Rosa (tel. 0586/905266; www.capraiavacanze.it) are the two vacation rental booking companies on the island.
A Night in Livorno -- Considering the timing of Capraia-bound ferries (they all leave Livorno early in the morning), you'll probably need to spend the night in Livorno before heading out to the island. A comfortable choice is the four-star Gran Duca, Piazza Giuseppe Micheli 16/18 (tel. 0586/891024; www.granduca.it); a stone's throw from the ferry terminal, it has well-appointed doubles starting at 120€.
