Hi Ken, we always do pre-authorization as deposit (NOT SALE) , this is just to hold your credit not payment for a while you stayed here. The bank may give the message shows "CHARGE or SALE" to make feel you have been charged but actually its not, I think it should be released back already.
If you have any questions, please feel free to contact us anytime.
Thanks a lot!
Whichever you might arrive here by HSR or Taoyuan MRT, finally, you also have to get to Taipei Main Station building then walking to here less 10 minutes. We are sorry that we do not have got any sheltered walk but we do have subway walk. But, I say seriously, we do not suggest you to try, even we local taipei people are easy to get lost.
GO taipei station then WALk here, it is you best choice.
