Mill Hill Broadway is a Zone 4 station in north London, served by Thameslink. Trains travel from Sutton and Wimbledon in the south to St Albans and Luton in the north. The line carries local commuters to several major central-London stations - St Pancras International is under 20 minutes away, with Farringdon and London Blackfriars just beyond it. There is also a connection to Luton Airport Parkway, taking around 25 minutes.
Mill Hill itself is a mostly residential area in the borough of Barnet, with Edgware to the west and Finchley to the east. The Broadway referred to in the station's name is a pleasant local high street that stretches away to the east, with plenty of independent stores as well as a few big-name shops and restaurants. A little further west, a cluster of green spaces - Mill Hill Park, Arrandene Open Space and The Mill Field - provides some balance to the local shops and housing.
