Hi All! I am moving to London in less than 2 weeks and due to the impending Christmas holiday period, need to find a nice flat within about 5 days after I land. Looking in the NW3 area, especially Hampstead. Since I'm not really familiar with how the housing market in London works, can anyone offer an opinion on what's more effective: booking several appointments with different agents for listings I find online or just picking 1 or 2 agents and having them take you around? Many thanks for the help!
