The stay at Diven's appartment was very nice. He and his wife picked us up at the Metro station (which is just 2 minutes away) and gave us a tour of the appartment. Also, they had filled the fridge with fruits and water/drinks for us which was all for free.
The apparment itself is very modern and has air conditioning in every room.
Since our flight was late in the evening, they kindly allowed us to stay longer.
If we will be in Taipei again, we would stay at their again.
