There were two hostel buildings, one behind the other, located just to the north of the East Compound main gate. I've written several pieces here about the place, but I wanted to post this photograph of a typical single room.
I believe the front hostel had mostly two-person rooms, while the one I lived in (in back) had single rooms like this one. It was slightly larger than it appears here because there was a combination closet/dresser/storage cabinet just inside the door and there was also a private bathroom with stool, sink and a shower.
The room was air conditioned and because electricity was included in the rent, I kept the place very cool during the summer months. I remember one weekend I noticed one of those large cockroaches, that seemed to be everywhere, coming into my room under the door. He stopped for a few seconds, apparently decided it was way too cold for him, and skittered back out again.
The hostel was adequate, fairly inexpensive, and just a short walk to USTDC and all of the Headquarters Support Activity facilities in the compound. I've circled the window in this photo where I believe my room was located. To the right of this photo, you can see some of the East Compound. You can just make out the striped antenna slightly to the right in the background that marks the location of the US Taiwan Defense Command building.
