Fiona is a great host (offering help with any/every concern and proactively offering to bring me masks during the coronavirus outbreak), the location is convenient (although different from where it's shown on the Aribnb map as of March 12th, 2020...it's still in Da'an and super close to Zhongxiao Fuxing MRT station), the wifi is very strong (50mbps up and down), and you get amazing natural light from the window. It's a fantastic studio to work from and very convenient to amazing food, Da'an park, public transit, and 7-eleven.
The space itself is not the highest quality, but if that doesn't matter to you then you'll be very happy here. Issues with the space that you should be aware of include: 1) the walls are very thin so it's easy to hear what's happening next door. Everything from the neighbors conversation in the middle of the night to their coughing. It won't matter if you sleep easily or wear earplugs. 2) the bed is pretty firm and can be squeaky. Again, didn't bother me, but you should know that.
