It is cheap, and most of the staff are really nice, but you should know a few things.
Cockroaches are common- I saw 3 in my room before asking to switch.
Some rooms are infested with little ants, even in the beds which makes it hard to sleep.
The younger staff are real friendly, the older staff just glare at you and don't even smile.
The bathrooms have quite a smell and are extremely (somewhat unbelievably) hot.
It is mostly used by Indonesian travellers. Only saw one other westerner.
So, if you want to save $$$, go for it. But know what you are getting into.
