I'm not sure if you need this kind of information
But if you need cheap hotel in Yogyakarta/Jogjakarta, I really recommend Wisma Ary's.
With just 230.000 rupiahs (around 20 euros) you can get beautifull room with AC. I was delighted with service of this hotel.
The hotel simply just beautifull and the staff was really nice. The building also not really looks like hotel since the owner are artist.
You can check their website here to get know this hotel.
Happy holidays guys!!
