Albergue Antiguas Escuelas Poladura de la Tercia
If the albergue is closed, head over to La Posada del Embrujo. They will help locate the keys. If they water is not turned on, they can also show you how to turn it on.
The Posada is also the place to go for dinner. They do a menu to dine-in or take-away and they have a vegetarian option.
