My Friend, I will recommend a type of hotel or guest house 14 kilometers away from Murree towards Nathyagali located near to Bariaan and the name of the place where hotel located is "Khera Gali"
There is complete peace of mind, natural beauty, calm, no rush and noice.Rooms are perfect with kitchen facility and a very long tarace as well, the cost will be around 1000 (Double room) but cable is not available withing the rooms but you can enjoy the calbe in drawing room.
If you are interest I will guide you further
