(4) Go through the archway, bear left and continue down the slight hill, then turn left onto Horseferry Road.
(6) When you get to a corner bearing right, you'll notice this car park on the left. Walk in between the silver and black fence, which is a walkway taking you along the Marina.
You'll see 'Hurford Salvi Carr' Real Estate agents a little further ahead. Turn right instead of going up the steps.
To continue, see step (7) of the 'Branch Road' directions, above.
