The Hotel is situated just up on the right as you pass the centre of the town heading West along the main road. Its a great place for a base although Cabrales is not as "social" as the likes of Potes which has a wider selection of bars and resteraunts. The couple who own it are top people and the bloke (cant remember his name) ihas endless knowledge of the area having written a few books on the Picos.
He normally recomends you give him a call when you arrive in Cabrales as the pathway to the Hotel is bery easy to miss.
