Highly mixed feelings. I booked the room at a great price and was quite happy with the view when I stepped by. The mountains on either side of the room, covered in snow, was everything I could wish for - right outside your window.
But there were major problems with electricity and heating.
Not sure whether it was just a temporary problem, but for a certain period, the generator was posing trouble.
Next, there were no geysers for bathing. Apparently, a solar heater was in place but it didn't seem to work and the water was still quite cold.
Finally, no room heating is included. A heater will cost you 400 INR per night. And I was fine with that until I got a wasted one that just wouldn't heat the room. It was snowing heavily and temperatures were running at around -3 degrees!
Saving grace, however, were the staff, and the food. Vicky was courteous and of great help. The in-house chef was quite great too. Make sure you have the tandoor-aloo-parathas there.
I won't stay with Treebo (in Manali) again. Too much pain. But if you want the best view out there in Manali, call them and confirm about amenities first.
