In general, this guest house building is quite pleasant when I stayed because it is in a private location behind the Ijen Suites Hotel (safe, comfortable, clean) except for the room I occupied no. 6, the minus is the bathroom which is not a decent size and is moldy, otherwise it is ok for those who like to exercise in the morning, the surrounding area is very supportive because it is in the luxurious Ijen area (if in Surabaya it is equivalent to Citraland)
