You have to go to
Old Town (Kota Tua)
Here's one fun activity you can do
Visit the Museum Nasional and Galeri Nasional Indonesia.
Don't forget to check out one of my favorite places
Suropati Park. I love spending my afternoon or evening in this park because it's a really fresh and quite place. Sometimes street musicians put on a nice show, which I enjoy, too.
Enjoy a meal at my favorite restaurant
Pecenongan Street. There's so much traditional food with great prices.
Here's a doable bucket list for you to do in one day
Taman Mini Indonesia Indah - it's a park with the whole country in miniature!
