This lovely penthouse flat in what looks to be a rapidly changing area is right by the Tube. Couldn't be more convenient to the easiest, cheapest way to get around the city(bar rush hour queues). We were met by an employee who answered our questions about how to operate in the flat, who provided some adapters in case we hadn't been fully prepared, and wished a good stay. It is 10 tube stops and a line transfer from most tourist sites so very very convenient. Also, within 2 blocks, there is a Waitrose, Sainsbury's, and a Tesco Express versions.
