Impa's House

Impa's House is a location from Ocarina of Time.

Features
The house is located in the southern area of Kakariko Village. The exterior of the house is the same as the other houses in the village, yet it is larger in terms of size. It has two distinct entrances: front and rear, the latter being only accessible through either the Hookshot or Kaepora Gaebora (from Death Mountain), and leads to the interior of a cage that contains both a Piece of Heart and a cow (who can only give Link milk if he's inside the cage as well). Although only one townsfolk is found inside the house during the day, at night it is inhabited by other villagers, such as the Cucco Lady and one of the laughing men. In Ocarina of Time 3D, the house is slightly revamped on the inside, where it now contains tips for playing, along with a map of Hyrule.

Even though the house belongs to Impa, she's never inside due to her duties as the protector of Princess Zelda. She actually left the house in hands of the villagers.

Trivia

 * In Ocarina of Time 3D, there is a book similar to the Book of Mudora from A Link to the Past.
 * If Link steps on the pillow upstairs, he will find a red Rupee.
