Very bad experience. The position near Stasiun Klaten is good, but it's a guesthouse with a different name and not a hotel. It's very hard to find on maps, and once there there is no sign that it's RedDoorz. The room was not clean, and I had to remove a lot of dust and disinfect everything. The bathroom was in terrible condition, no window and a very strong smell of mold, with hairs of the previous guest clogging the water drain. During my stay, the room and the bathroom were never cleaned by the staff, and I had to ask for the clean towels. The owner also imposes to leave the shoes outside of the house. There is no toilet paper or other amenities.
