Yu-Sheng and his grandmother were very welcoming and friendly hosts. We had to spontaneously book this room (1.5 hours before we arrived), and thanks to Yu-Sheng's flexibilty, this was not a problem at all.
The place is well located directly next to the MRT station and from there it's a 20min MRT-ride to the city center. WiFi and air conditioning were working well.
We can definitely recommend to stay at this place.
