We stayed there for one whole week in middle October, 2018 for the 4 of us. The place is in absolutely the best location, within walking distance to MRT station and many amazing restaurants - Portuguese, Japanese, Chinese (of course), German, and Vegetarian.
The place is very clean with many convenient features, and our host Jan was very responsive to our messages and questions. Having a super large living room and dining area with hot water for tea and coffee, makes it so much easier to have conversations with multiple families, in comparison to regular hotel stays.
Street noise was not a problem for us in this busy area, as windows are very sound proof. But if you really want zero noise, have ear plugs ready.
Shopping was also very convenient, and when MRT was not the best method, calling taxi to go anywhere (such as night market) is usually less than $5 USD.
We will definitely stay there again on our next trip to Taipei.
