When you arrive on Bonnington Road lane you need to go down to the end of the road - you will see the storage centre straight in front of you. Whilst facing the storage centre you then turn to your left and go down the driveway a short distance to the end. You should see a Wicked sign here but if not, just turn right and we are just along there on the right again.
Bus number 11 from Edinburgh city centre leaves every 12 mins and takes approx. 10 mins to get to Bonnington Road Lane, so super central! The bus stop in Edinburgh city centre you need is on George Street and is bus stop 'GL'. This bus stop is at the George Hotel which is 50 metres from Saint Andrew Square. The bus stop you need to get off at, closest to the depot, is called 'Bonnington toll' - this stop is outside of Rosebank Cemetery. The stop itself is on Pilrig Street, just before Bonnington Lane. Once you get off the bus walk up to the intersection 30 metres away, turn right onto Bonnington Lane and then Bonnington road lane is the first road on your left. Then follow the instructions above.
From Edinburgh airport the best public transport option is to get the airport shuttle bus to the city centre (they depart approx. every 10 mins) and then jump off at the George Street stop. Continue walking up George Street the same way the bus is heading for another 200 metres and you'll find the bus stop for bus number 11.
