Yu’s place is a perfect base to visit the National Palace Museum(國立故宮博物院), Shilin Night Market士林夜市) or Beito(北投) hot spa. Situated in a good residential area, has 3 locks to enter the room. You can see the platform of Zhishan station (台北捷運芝山站) from the entrance of the building.
Yu answered promptly to my questions. He helped me a lot in checking in procedure and showed me around the neighborhood.
One caveat might be that the studio apartment is on the 3rd floor and you use a staircase to bring up your baggage. The room has electric kettle but the fridge is in the shared space. Since Sogo department store, Carrefour supermarket and many eating places are within 5 five minutes walk, you have numerous options for your meals. Also, Sogo has a Din Tai Fung（鼎泰豊) branch in the basement floor, which I highly recommend.
