I spent four nights at Aapo App Homestay. Everything was excellent: the room, the food, Shevi's advice. Aapo Aap's location is a bit inconvenient; but you can hire a cab to down town Shimla for RS 300 (>$USD 6) one way. Shevi provides excellent advice on the tourist attractions around Shimla. I highly recommend Aapo Aap Homestay!
