Speak with friends and family already there as a starting point. If this is not an option, have a look at some popular flat hunting websites such as SpareRoom, Gumtree and Kiwis in London.     The Kiwis in London 'Live Flats' link will give you an idea of the current going rates. Expect to pay a deposit and 4-6 weeks rent upfront when moving into a new flat.     West and South West London have long been popular with Aussies and Kiwis - Shepherds Bush, Acton, Hammersmith, Putney, Southfields, Wimbledon, Wandsworth and Clapham.    Wherever you decide to live, just make sure it is close to public transport – London Underground, buses or trains.
