Overall it was a great place to stay. Access to such expansive private outdoor space was fantastic, and Kate was extremely responsive throughout.
Though there were two outstanding issues that became problematic during our stay:
Obviously, mosquitos are a fact of life in Taipei, but we were surprised to see such extensive measures in place at Kate's to manage them (i.e. electric traps, several citronella candles and copious bug spray provided), and wake up with many more bites every morning than expected.
As it turns out, there is a neglected corner of the roof patio with accumulated gardening detritus and roughly 4cm of stagnant green water sitting atop a broken plastic tub. I would think taking care of this would dramatically reduce mosquitos on the roof.
Otherwise our stay was great, and would certainly stay here again should the mild pest issue be addressed.
