In Indonesia there is a wide variety of accommodation available from staying at local peoples houses till five stars western hotels. The prices will also vary from about 5,000 rp for a homestay till over 500,000 rp for a first class hotel in a city.

In the tourist centers you have a large choice to stay. The western higher class hotels don't have to be much explained. They are comfortable and you have all luxury you can expect. Of course also the prices are first class.

There is a wide range of mid class and bottom end hotels. In the tourist areas you can find hot water while in the outer areas you only have your own mandi. 

Very basic are also the "homestays", which means people do let some rooms of their house for tourists.

Losmen or "penginapan" are very basic hotels. More comfort will give the "wisma". A wisma is a mostly family run guesthouses with a very good service. In many cases you will have your own toilet and mandi and in tourist areas often there is a western shower.

Mandi

Mandi means bath or bathing and is a typical way to wash yourself. The kamar mandi or bathroom contains a big tank filled with water and next to it you can find a plastic kind of plastic saucepan. The Indonesian way of bathing is to take the water with the saucepan and splash it over yourself. The water tank is not meant to sit in because you pollute the water and mostly the water is refreshed only one time a day, sometimes less. Also the mid class hotels at the bottom end and homestays have this way of bathing and mostly the " kamar mandi " is a shared one. Toilets (kamar kecil) can vary from the western toilets till just a hole in the ground. The traditional Indonesian toilet is a hole in the ground with places on both sides to put your feet and then you have to squat and aim.
Indonesians also do not use toilet paper. The use their left hand and the sauce pan known from the mandi to splash a lot of water around. (That's also why it is not polite to give an Indonesian something with your left hand). So buy toilet paper yourself but if you use toilet paper be sure you flush the toiler regular because the plumbing system is not calculated for toilet paper and is easy plugged.
