Wanted in Rome and of course live in Rome are also good websites for flats etc.
In Italy you pay less if you do a flat share (i.e. sleeping in the same room as two or three others) but I couldn't be bothered and got my own room.
The only problem with that is the price - 400 - 500 euros still goodluck.
