This was my first room in Taipei, roughly 7X12, $20/night, shared bathroom in the hall. I moved later to one with only one bed. It's in a hostel called "Happy Family" just a short walk from the Taipei Main station already pictured. That station is a huge multilevel complex, mostly underground including the main MRT station, the main railway station, the main bus station, multiple underground strip shopping malls with connection to a very upscale mall and food courts. It reminded me of an old computer game called "Adventure" or "Colossal Cave Adventure" involving a kind of 3-D underground maze except this is the real life version.
Another thought I had, considering the extremely low birth rate in Taiwan, this may become an amazing urban ruin some day, ah well future generations may see it, not me. But I find it interesting to visualize this giant rabbit warren in that state.
