Comfortable flat in walking distance (pleasant walk across a footbridge over the dock) of ExCel conference centre. Sam replied to my queries quickly and I found the Concierge for the flats easily (right next to the DLR station). Loved the DLR - especially sitting in the last carriage at night looking back at the London lights - great for the centre of London as well as another way of getting to ExCel and felt safe travelling on it. Also enjoyed a trip across the Thames on the cablecar which is near to ExCel. Would recommend Sam's flat to anyone at an ExCel conference or visiting central or east London.
