I have been travelling for 5 months througout Vietnam, Cambodia, Japan and the Philippines, and the Burnham Baguio was the worst hotel, by a long shot. The rooms were grimy, dark and dingey. The carpets were threadbare and the whole place run down.
Thebathroom was so bad, I waited till moving to the Prime Hotel (up the road a bit) before showering the next day.
I booked for three nights, and left after one. If you are travelling to Baguio, do not stay here.
