It is about 5minute walking distance from 2 popular MRT stations. The facility is a city owned sport center with 5 badminton courts, and a lot of other indoor sports facilities such as archery, basketball, golf, table tennis, swimming pool, etc. They charge quite reasonably for court usage, it's air conditioned. Oh, another plus, is that there's a badminton shop right on the floor where the courts are at. They sell all badminton related products and accessories. Racket prices are very reasonable as well. They sell Yonex, Victor, Flypower, MMOA, Fleet, etc. It's worth the visit Have fun when in Taipei!A
