Advice on finding apartment in Taipei

Hi, I will be in Taipei for two months from the end of August and am looking for a studio apartment or self contained room to rent. Does anyone have any suggestions on how/where to find a place to rent for two months?

I will be doing a Chinese course near the Gongguang and Taipower Building MRT stops so in this area would be ideal but as long as it's near a metro station it should be ok.

My requirements are pretty basic; a bed, bathroom, desk and WiFi and ideally priced under NT20,000 per month if possible.

I would greatly appreciate any advice you can provide. :) Thanks a lot!
