Coming back after 9 years, any tips for a former ex-pat?

I’m coming back after 9 years away and could not be more stoked! I lived in Taipei for 2 years and loved it so much, and now a wedding is bringing me and my girlfriend back for 8 days at the end of October. I’m sure a lot has changed since 2017, so looking for everyone’s advice on a few different topics:

Airbnb vs. Hotel:
I’ve seen a lot of talk about illegal or catfish Airbnbs and what to look for in listings. If the property is rented by a Superhost, does that add legitimacy to the listing? I’ve found a few good options, but have been more hesitant to book after reading some other posts on this sub.

Areas to stay:
Looking to stay somewhere with shops/cafes around and close to an MRT. I’ve seen a few people recommend Zhongshan so we’re looking there. I always loved the Zhongxiao Dunhua area. I think we’ll avoid the noise and crowds of the Ximen area. Are there other places we should consider?

Things to do:
It’s my girlfriends first time in Asia let alone Taipei so I want to hit all the major tourist spots, and also go places I used to go to when I lived here, but what are some other things that are new from when I left that I shouldn’t miss? Is baseball still in season? Planning some excursions up to hot springs in Yangmingshan and seeing Jiufen, but hoping to have lots of options while we’re in the city.

Appreciate everything you have to share!
