Hi, I'm moving to Tokyo in a month or two with work and would appreciate some local advice on where to live in Tokyo. My rental budget is pretty good (300-400k a month) and I'm looking for something in central Tokyo that Roppongi-itchome station is easy to get to. I'm a single Australian guy, not really into night-life that much, so some suggestions outside of Roppongi would be very useful. Even though I'm moving there on a permanent basis, I've never actually been to Tokyo before!

Thanks in advance.

P.S. The "how to ..." youtube videos are very useful. I'm sure that's saved me from doing a couple of embarrassing things already.
