I revisited Sloane Square station on 17th March 2023. It does have an escalator from the platforms travelling upwards. There are zero lifts.
If you enter the station to travel anywhere, there are 50 steps, a lot of stairs down.
At the Sloane Square station, there are elevators from both platforms to street level when leaving the station.
If you enter the station, there are steps only down to the platforms, about 50 steps.
Outside the station is the number 11, 19 or 211 bus which heads to Chelsea Old Town Hall in about 4 minutes, or a 20 minute walk.
The 211 bus travels via the roadworks in Kings road, past the Royal Brompton in Sidney street, and then turns left past the Royal Brompton, Fulham site / Royall Marsden.
There are lots of roadworks still in this area along Kings road in November 2023.
Also, immediately outside the station is a section of road which looks like a walkway, but traffic treat this as a normal road at 30 mph.
