St James’s Park Tube Station

It’s a nice straight forward station — only stairs to access the platforms but not too many. The countdown both shows the train times and is accurate. Exits from both ends of the platforms. Announcements are understandable.
Pretty much what you hope for from a tube station.

Servicing the Circle and District Lines (between Victoria and Westminster) in Travelcard Zone 1, St. James’s Park station is directly underneath and attached to the headquarters of the London Underground itself. It’s also quite close to famous New Scotland Yard, down the street.
It is not step free and as a Grade I listed building, that’s unlikely to change. Otherwise, it’s an «A-​OK» station that does a fine job of transiting passengers without hassle. There are at least three different exits — Park, Broadway and towards Victoria Street.
Over the years, it’s been known as «St. James’ Park», «St. James Park» and is now officially «St. James’s Park». There is apparently still a roundel on the platform with the original name — try and find it!

Always difficult to give a tube station a starred rating, but here goes!:
A two platform station in Zone 1, between Westminster Abbey and Victoria and near Scotland Yard and the beautiful St. James’s Park, it serves both the District and Circle Line, with common destinations being Richmond, Ealing Broadway, Tower Hill and Upminster. It’s also home to a large contingent of TFL workers in the offices above.
The station has two exits, the second for the offices around Victoria Street open only during rush hour (weekdays from 7.30am — you can see the people queued up here looking at their watches at 7.29am!), the main one leading you out of the building from the iconic 1927 Charles Holden listed art deco-​esqe building, that in its time was groundbreaking — it was for some years the tallest building in London.
Just outside the ticket barriers are approximately 10 shops, including a Carphone Warehouse, a general food/​drink shop, a cobbler, a newsagent, a touristy magazine and postcard shop, a suitcase shop (!), a small photograph developer, 2 cash machines, several cafés and a recently-​opened juice bar. There’s also a Post Office, Pret-​a-​Manger, pub (with gourmet sausages!) and a Japanesey type restaurant (not sushi) just outside the building and a Starbucks outside the second exit.
Difficult to say how good it is compared to other tube stations — but it’s clean, the staff are (generally) helpful, it’s never too crowded, trains run every 2 – 3 minutes and you can always get a drink and something to eat nearby — so I’ll let you make up your own mind!
