The Diamond District is not only where the TWI office is, it's also where we're all staying. There are four corporate blocks and 17 (?) residential blocks. The layout is sort of a hollowed-out 'L' with a courtyard in the middle, as seen here.
The entrance to 'C' block, which is where I live. (The entrance to 'B' block is here, too, but we don't care about that.)
The entrance to our two-level flat is on the seventh floor. Note the lack of 'G' or 'B' buttons.
View as you enter the flat.
Classy.
Seating area, with my clothes drying outside.
