In terms of location, this place might not be at the heart of the city but convenient enough for you to hit anywhere quickly with the aid of google map. Songshan railway station (not referring to the metro) is walking distance and allows you to take day trips out of Taipei easily.
The hosts have great protocol for making check-in/out a breeze. They received me on arrival and provided me a brief orientation of the house and the area while they equipped the house with a self-made guide to the area. If you look carefully, there is also travel books on Taipei on their bookshelves as well. They are most thoughtful and helpful. When I made a last minute request for a private sedan to the airport, they made the necessary arrangements without complaint.
If I absolutely have to really pick on something, it is that the listed facility of "gym" only has treadmills. That might be a letdown for some of you who wanna ensure you keep fit during a holiday. But I'll gladly trade that for the thoughtful hosts I had for this stay.
