I had read many positive reviews and decided to stay at this hotel for my recent three-night business trip in Jakarta. Everything went smoothly at first until I was awakened by some loud chanting at 4am. The chanting sound was so loud that it was impossible to ignore, like someone's singing outside of my window. It was a little past 4am, I called the front desk, and was informed it was the daily prayers from the nearby mosques. With all due respect, with this kind of surrounding sound, there is no way I can have a good sleep, especially with jet lag. I spoke to the staff. The gentleman was friendly and offered to bring earplugs.
The second night, I asked to move to the other side of the hotel and a higher floor, and was awaken at the same time. The chanting was even louder than before!
It turns out this hotel is surrounded by at least three mosques... So I was not surprised when the same thing happened again the following night. At that point I was just too tired and felt happy that's my last night at this hotel.
This experience prompted me to write a review, which I rarely do, to give a head-up to the newcomers. Think again if you need undisrupted sleep and are not used to this kind of daily rituals. Otherwise, be prepared to be sleep deprived during the whole trip like me.
I do think the hotel should try to improve its soundproofing of the rooms and give some fair warning to people that are not familiar with the situation.
