Just got from Bandung, Did not do anything except shop!
Weather is great, cool and comfortable. Almost like an air con room.
Rained lightly but quick durations.
Most shops sell fakes but you do get really really nice stuff in between. I do believe they're genuine. So ie.. Search and you'll fnd discounted original clothes.
Rumah mode and riau and one at merdeka were good. Some malls have good sales too.

Food is cheap comparatively..

Getting around is easy on an angkut, only 2000rp. Sometimes they ask for 3000rp. Just ask them before getting in to confirm your destination. Can get in and out at ANY place, so that's convenient.

Taxi is expensive because they have a minimum fee of 25000rp.

Airport is really small so best to "rush" to immigration once you arrive. Only 3 counters available!

Another nice thing is there's basically no language barrier.
