Yu was a very accessible and welcoming host, who contacted me often in the crucial last day before checkin, make sure that I could make my way to his place. It's not always easy, given the language barriers involved, but even a regular visitor to HK like myself appreciated the details. He explained everything about the apt which was of primary and secondary import, and then left me to be for the duration of my stay--the place itself was spotless and stylish, with a wonderful and unusual harbor view, in a good location and a safe building.
