The room is large for a 300,000 Rupiah room. There are two elevators, both of which work. The water tends to smell of chlorine, so those with sensitive skin might be wary. The hot water is hot. Despite being close to the mosque, we didn't hear much of the noise during our stay. The room's soundproofing is also good; my sister couldn't hear the sound of her hairdryer from outside. There's a pool that looked clean. There was live music in the breakfast hall, which was quite audible from the 4th floor. Perhaps due to the overcrowding, the cleanliness was a bit off, and it could be improved upon, as we found orange peels on the floor, but overall, it was good.
It's worth it.
