The check-in and check-out process was quick, but unfortunately, the hotel lacked cleanliness—there were leftover food crumbs on the carpet that hadn't been cleaned, and an oxidized blood stain on the bedsheet. On top of that, every time we used the hairdryer, even briefly, the power would trip. When we reported this to the front desk, the response was extremely slow; it took over 30 minutes and three phone calls before an engineer finally arrived. The train noise was also very loud, despite our room being on the 9th floor. We won't be returning, as it was very difficult to get a good night's sleep during our business trip to Jakarta. Far below 4-star standards.
