Tastefully converted from a private house, this 1911 landmark has become a big favorite for quick rail-getaway overnights from Bilbao—the 37-km (22-mile) train ride out is spectacular. Guest rooms are charming and comfortable; those upstairs have balconies with marvelous views, and No. 22 is the best room in the house. The breakfast room is cheerful and light. There's also a sauna.
