When we arrived we were a bit disappointed with the décor. The apartment could certainly be described as "basic" in terms of the quality of the fittings and furniture.
We had to get someone round to look at the A/C which wasn't working in one of the rooms and to replace some lightbulbs but, in fairness, they were pretty responsive.
The location is very good...right in the middle of Da'an very close to SOGO, lots of bars/restaurants/shops.
The hosts were friendly in person but somewhat paranoid before we arrived, e.g. wouldn't give exact address and wanted a precise arrival time.
Overall it was OK but we have stayed in better apartments in Taipei.
