I had a great stay in the Sheraton Bandung. AFTER their renovation :P
I had a great stay in the Sheraton Singapore. Upgraded to Cabana Room. Good service. Great lounge
I had a so-so stay in the Sheraton Yogjakarta. Nice big property and friendly helpful staff and yummy breakfast. Huge upgrade to one tier below Presidential. But old old old. Balcony wood rotting, iron rusty - made me scared to lean on it. Toilet water seal not consistent so sewer smells. Chairs and sofas had a few stains. Pool had algae on the tiles. Would I go back? Only if I was visiting Borobodur. Worst hotel? Nah... paid like $75 or somesuch for a 1000sq ft room.
