I read the reputation on both Expedia and Google before I checked in, and found some people say there are so much noise from the street in front of this hotel. Some say you can't sleep enough. However, in reality, not that bad: I took tight sleep every night (in weekends, a bit noisy, but anyway, I slept deeply enough). So, for those who are reading the comments, don't worry too much.
Overall, I enjoy this hotel; very comfortable. I also would like to mention (like those already pointed out in their comments), the service was amazing! Every staff I talked was so kind and helpful.
If I have to add something I'd like this hotel to improve, I couldn't use the security box in my room, so I appreciate if you check later.
Thank you for everything. I'd like to stay again next time I'm in Jakarta.
