The area around Prince of Wales is nice. While yes, Shatin is on the same train line as Fanling and Sheung Shui, your hospital is across the river, maybe a 15-20 minute walk or so from the shatin station. It's much mellower than the area by Shatin MTR. That said, things around there are pretty local - I wouldn't expect people who live near there and have a room to rent out will be reading expat sites, nor would I know how to reach them. Like others have said, 2000 really isn't much around here, and that area isn't the kind of place that would have tiny subivided apartments.
