My accomodation so far has been around £370/month not including bills and I've lived in Clifton and now Cotham.
Use some estate agent websites to search through properties by group size, the earlier you get this done the more likely you are to find a house with the amount of rooms you want. Also consider the deposits and agents fees (around £150 to sign a few pieces of paper).
There is unfortunately a fair amount of being screwed, such as being charged £180 for cleaning the (spotless) flat, an extra charge for cleaning the outside of the windows, repainting the (mouldy) windows, filling in holes (made by the landlord putting in coat hooks)
