I did mean Stansted but admittedly it’s probably the least convenient airport from Central London unless you live close to the Liverpool Street line — personal bias led me astray. London City is of course closer from many points within London but is much smaller. That said, London’s other airports are also relatively convenient, e.g. Gatwick and Heathrow via tube, Thameslink or dedicated trains.
