Used to be a waterspring, water surrounded leisure palace for the first Sultan of Jogjakarta. He would sit on top of the tower to see his concubines chat, giggle, having a bath (voyeuristic much?). Sultan used "kenthil" flower to be thrown to one (or two, or three, or more, one will never know) of his mistresses as a cue that she's chosen for that night. The beds, the guide showed, were fixed and built on top of a flowing river, a natural air conditioner. Other beds had fireplace below them to keep the beds warm. Very rustic, Tamansari that you see today is a reconstruction from 1990s, imagination of the real one.
Today's function: tourist attraction, playing field for the local kids, home of the first cyber RT (RT 36 Tamansari) in Indonesia; it has wi-fi for the whole neighborhood, also video clip and pre wedding shooting location (err...among Bondan Prakoso and Darwis Triadi's favorite).
Ullen Sentalu
No doubt, the best museum in Indonesia. Lesson learned: leave museum and its maintenance to private owners. Also, there's a big chance that ladies will have a new hero after visiting Siti Nurul Kusumawardhani a.k.a the Ideal Princess' room.
Taman Pintar
Have you ever cursed the non-existence of public place in Jakarta? Too much malls? You'll curse even more knowing Jogja has Taman Pintar and Bandung has Taman Lalu Lintas.

Sendangsono
According to Santi Nuri, this is where they got high in "3 Hari Untuk Selamanya" (Playing Float on the background).
