I stayed in w5 best Hotel for 7 days, it was easy to find out, opposite Hotel Papa Whale, not too crowded but easy to visit Ximending area and grab some local food or snacks. You can take an MRT from Ximen station to anywhere in Taipei! The room size was suitable for 1-2 people and the facilities was quite nice. The bed also comfortable, the maid provided 4 bottles of water per day, refilled the minibar and bath stuffs completely. The flaw was the towel, the hotel did not provide the bath towel but instead provided the paper towel for single use. It was not convenient for me. Moreover, you can see the night lights and mountains through the window, the view was so fabulous.
