Thu was a great host! He let me arrive early, and had a friend at a nearby restaurant give me the keys. And the friend walked with me (80 meters or so) to the apartment.
The apartment was spotless, and in a great location. Minor nit to pick: the Internet was a bit shaky. It kept resetting. Irritating because Skype calls kept getting cut off. I'm sure Thu would have looked into it if I had complained, but I didn't have time because of other activities.
