Maida Vale Maida Vale ( ) is an affluent residential district comprising the northern part of Paddington in west London, west of St John's Wood and south of Kilburn. It is part of the City of Westminster. The name derives from the "Hero of Maida" inn which used to be on Edgware Road near the Regent's Canal. The pub was named after General Sir John Stuart who was made Count of Maida by King Ferdinand IV of Naples and III of Sicily after the victory at the Battle of Maida in 1806. The area is mostly residential, and mainly affluent, with many large late Victorian and Edwardian blocks of mansion flats. It is home to the BBC Maida Vale Studios.
