The hostel is very near to Taipei Station just a few minutes walk there. However, finding the location of the hostel is a bit difficult as I cannot find any obvious signage showing the exact location of the hostel. If you are the first time there, make sure recognizing the wholesale shop 光南大批發. The hostel is just at the 6/F of the shop building.
The reception is good and helpful, you may also check in in 24hrs that means when you are sleeping inside your cell, you may be disturbed by those late comer. Anyway, the cell is clean and you may also know friends mainly from Korea, Hong Kong and Japan (only because I'm there during winter, not sure the hygine and room condition during summer).
One problem is that the shower cubicle for girls are not enough and the drainage seems not work very well, make sure you bring all your slippers, towels, shower gel, shampoo etc. as the hostel provides with charge.
The room is big enough to put all my personal lauagges. Will visit again if I travel alone next time.
