4. bandung is no longer the bandung before due to the desforestation.
5. its climate is getting hotter each day.
6. not to mention its traffic, pretty jam up too.
Even with the deforestation Bandung is still a nice & cool place. The highway that they opened has made Bandung more easily accessible & that's why traffic is bad especially during the weekends with many visitors from Jakarta.
If you want a more pristine environment just go a little further up to the mountains to Lembang. It's boring but quiet place but you will need a car.
