Hotels near Merapi camp ground

I stayed in a Lawu room (glamping style). Notes for improvement: 1. From 8 a.m. to 11 a.m., the room felt warm and hot, perhaps because the glamping room is a tarpaulin style. I just now understand why they provide two air conditioners (split and portable). However, around 12 p.m., when the fog starts to descend, it becomes cooler and cooler again. It would be nice if there was an additional heat-resistant layer on the outside of the glamping room. 2. The main breakfast dish (chicken) was very slow to be refilled, running out several times and having to wait for another one. However, I appreciate the restaurant for making it. Besides the two points above, everything else was excellent. Complete facilities, friendly and responsive service. Thank you very much.
