Great little house, even better than I expected. Spotless and well equipped. Great location, only 5 minutes walk from Paddington-you reach anywhere in central London in less than 30 minutes. Lovely local pubs and restaurants.
About the host-well I didn't get to meet the host face to face, but she was super kind and eager to help.
However, I found three minor issues about this house. Well, the first two are things that the host really can't sort out, but still. First is the lack of a lift, and you have to climb quite some stairs to reach the flat. Second is the blazing-hot-only, feeble water tap of the sink. Third is the cooking utensils; there are only two sauce pans, that's all, no pan or anything. That could be improved.
Though I described the flaws, I've got to say that this still is a great airbnb, and I definitely want to come back. When I come back to London again, I'd definitely consider staying here again
