We spent one night in Kavah Ijen Inn. Very simple and clean hostel, but it has everything you need. Set in middle of village near Licin, rounded with nature and rice fields, habited by very friendly people.
In our price we had rooms, transport from train station to hostel, transport to Ijen, entrance fee, masks, trek and transport to ferry. And the most important: wonderful guy who took us to Ijen Crater, sulfur miner with opened hart and mind! Best friend we could meet on our way: Sam. He gave us more we expected! We recomend trip with him!
