Great hosting with quick answer!
Apartment is quite old but inside of place is nice and clean condition. But the door lock is quite difficult to use, once you lock inside, you cannot open with the key outside.
Convenience stores and markets are only 3mins away from the place, so as subway station. But there is some distance from the downtown or sightseeing place other than Taipei 101 building. It was ok for my family since we mostly take the taxi or Uber.
Most likely, my family had really good time at the place!
Hope to see you again for next trip of Taiwan:)
