Any particular tips or suggestions? Lodging, restaurants/street eats, things to do?
How about transport? As I've mentioned elsewhere, I'm wary of Grab/similar because of long wait times and cancellations. Hoping this gets better eventually as the car hire services adapt to Covid.
This is mostly or entirely pre-Covid, but possibly of interest. Possibly paywalled.
You saw our video right? Our video gives you a good day's worth of activities.
I can't speak to the situation with Grab as my family provided transportation. I imagine it's no different than any of the other major cities. You'll more than likely run into the same issues with cancellations or long waits....and that's probably more of a result of traffic than the drivers themselves.
You can also use Klook and hire a driver for the day. I just checked and it's only $28 for a full day. We used Klook in Bali and in Yogyakarta so it's reliable.
As for things to see. Depending on how long you'll be there I would most definitely visit Tangkuban Prahu, Kawah Putih,, and any of the tea plantations in Lembang.If you want off the beaten path where no foreigners go but is super amazing then go to Tebing Keraton early morning for a crazy cool sunrise with fog.
As far as food places go, it's basically a pick any place you want. There are so many places to eat in Bandung that no matter where you go it's going to be good. But if you need a suggestion I highly recommend Sindang Reret. Very traditional Sundanese restaurant. Because you are in what I'd consider a non-touristy part of Indonesia I'd probably stay away from street food unless its served piping hot and in a new container vs. a dish that's been "washed". Definitely try out Kue putu, Martabak Manis, Martabak Asin, Cendol,....and the list goes on and on but those couple of things should get you going. If your are a meat lover like myself then you cannot skip out on Sate Buntel. Just look it up and you'll know what I mean. It's hard to find but if you do find it then....my mouth is salivating over it right now...lol.
Lodging is dirt cheap in Bandung so you can splurge for an Accor, IHG, or Marriott branded hotel near any of the hotspots and you'll still be only expending $40-$75 a night. We stayed at Pasar Baru Square Hotel since it's right next to where my family lives but if I weren't staying there I'd stay further up closer to the mountain around the Cihampelas or Dago area.
