If you know your way into Waverley from the top end of Leith Walk, to the Eastern entrance it's quite an easy trip with using lifts to the station. So quite User friendly. Not so much if you use the stairs. So Picardy Place could be an interchange too. St Andrews Square to Waverley is just as challenging an interchange.St Andrews Square would be the closest tram stop to Waverley. Picardy Place tram stop is going to be located in the middle of a roundabout, so it's quite hostile for pedestrian access, unless you enjoy waiting at traffic lights.
