This was a very good stay, made great by Min's thoughtful advice and helpfulness.
Min's place is within short walking distance of the metro station and close to both Beitou's main attractions and local restaurants (5 minutes to metro station, 10 minutes to Geothermal Valley). The room is spotless and, although the bed was hard as is often the case in Taiwan, quiet at night.
More importantly, Min was incredibly helpful. I wanted to hike in Yangmingshan and shared my plans. By the end of the day, Min offered for me to come along a hiking club and I was able to enjoy a nice hike along with a very friendly group of Taiwanese. I never imagined I would have been able to experience this and am glad to recommend Min's place to other travellers looking for a good place to stay in Beitou with a great host.
I especially recommend at least looking at Min's advice regarding local restaurants.
