This could be a general issue with SE Asia, but one thing that was a breath of fresh air for me as I departed Jakarta from my Bali trip last year was a thought that I no longer need to worry about quality of water being used to wash salad veggies or clean my toothbrush with.

Clean safe water from the sink was definitely not something I experienced in Bali in 2024 and I had the similar impression in Jakart

I traveled often between Jakarta and Japan in 2018, 2019 and 2020. The real breath of fresh air for me was literally the fresh air back in Japan. After running around for a week through Jakarta, I would inevitably develop a deep cough and a clogged nose. That said, the people, the food, and as someone else pointed out the nightlife is amazing.
