I was in taipei with my girlfriend, her parents and younger brother. Reserved all 3 rooms. The rooms were really beautiful and the host provided much useful information regarding directions and the weather. They also took initiative to follow up before/during/after the trip!

Plus:
Very spacious and accessible to Taipei main station/Zhongshan mrt.
Host was able to accommodate early check in the morning as our flight arrived in the morning.
Soap/shampoo, washing powder and washing machine provided.

Minus
No lift. So if going with older folks then can be a problem as there are only stairs.
Shower water flow can be slow but the heater temperature was great.
The sound proofing between rooms was bad. So the sound of our TV could be heard clearly in another room.

Overall it was a very positive experience and I will greatly recommend this apartment.
