Not a student but my sister goes to SOAS.
She hates it. She didn't like the people, and found that whilst she wanted to go out and explore lots of different things - museums, bars, different music venues - it was was difficult to find people equally enthsiatic about going out and trying things out. It was also difficult to just meet people in general (not sure why though, didn't ask). Eventually she found herself really depressed at the place.
She hated it so much that at the end of last academic year, she was looking for a new uni to start at, but, despite getting a place at one she liked, for several factors couldn't move.
Really, really not meaning to put you off, but I just wouldn't like anyone to have the same experience as her. It's possible that it was just a personal experience for her rather then a general one, but even so, please do your research before going.
