The Train (both ways) had plenty of seating available and was easy to navigate, at Gatwick Airport and London’s Victoria Station.
It was comfortable and there were accessible charging points throughout. The journey was very direct, with only a few other stops each way.
Although slightly pricey, accepted as I was aware of it’s access into the centre of London, I would happily use this service again, recommending it due to it’s simplicity of use.
