This is the best accommodation.
It's very clean and affordable. The mattress is comfortable, firm, and doesn't hurt your body. I got a cheaper price from Traveloka than booking directly.
Highly recommended.
The only problem is that the staff took a long time to arrive. When checking in, I had to call first, which took a while. There's only one spoon in the living room, so I used it for coffee and sugar, and I was worried it might be used by someone else. But this is a cheap and clean accommodation, located right next to the Dieng Mosque.
It's really comfortable.
