Bandung is a little sleepy, except on weekends and holidays when half of Jakarta seems to descend in droves. They've had some epic traffic here the last week. Last week it was over 31 degrees celcius before the rain cooled things off.
I'm actually at the Hyatt here right now, which is a very nice property, with great staff. I spent New Years here for just 5k points a night.
Too bad it's leaving the Hyatt family on Feb 1st.
There is a hot spring, Japanese tunnels, Angklung musical performances and lots of other fun stuff to do. They have Uber here, too.
