Yes, google is handy for seeing flats and working out prices. Seem to be plenty of english friendly rental property sites as well. Not so clever at the moment trying to sell me teenage female fashion.

I'm more interested in views on personal experiences of central Tokyo living. Roppongi is the well known expat hangout, what other places should I consider? Any comments on what sort of discount you could get in the current market also useful. In Hong Kong where I live at the moment property is booming but I think that's not as likely to be the case in Tokyo.
