This was a great experience, Willy's host was good and welcoming. I spent 4 days 3 nights in Taipei for a buiness trip. And the first night he waited outside for me because I couldn't find the place.
The place is about 20-25 mins walking distance from the blue line MRT station. It is located in an apartment and a single flat and the facilities are exactly as described. Willy allows tenants to use the kitchen, TV, PC, washing machine, airconditioner and fans. There is kettle and hair dryer as well. I believe that I have got most I need.
There are some 24hrs convenient stores and restaurants near the place about 1-2 streets distance, and a 全聯 supermarket about 10 mins walk. I had my breakfast at a lotte shop with breakfast, really worth to try.
Although I wouldn't say that it was perfect clean but very tidy. Willy has made it as a cozy place for each tenant to ease their stay. I would recommend to stay and visit it again.
