Peach Blossom was one of the many places I visited during a Jakarta trip. It's located in a complex referred to as Roku Robinson along with several other places, although I'm not sure which other ones are hobbying venues apart from Griya Sehat Spa.

Roku Robinson was easy to get to by taking a rideshare (Grab) to the Great Asia Hotel. Facing the street with your back to the hotel, walk to the left, then turn down a small road, then turn right and you'll see a prominent black sign jutting from the side of the building.

Here are GPS coordinates:

I arrived around 5:45pm which I believe is too early. The mamasan spoke almost no English and I couldn't get much information besides a price quote, which was 440k rupiah. Next time I'll use a translation app and try to get operating hours.

There were only two ladies immediately available, neither of which was attractive but not ugly either. One was a little overweight. A third one came in that looked better, but overdone on the makeup. I didn't really get a good look at her.

I'll need another visit in the future to get a better feel for the place but the initial impression was not that good.
