I stay at kurla and it will take u almost 15 minutes to reach LTT by foot. U just need to cross the foot over bridge at Tilak nagar station and from there a walk of 2 minutes to LTT.If u want to reach directly,then u can take an Auto which will charge u around 40-50rs.Even the auto will take 15 minutes as it has to take the Eastern express high-way route and then get to LTT.Or else u can hire the share auto just outside the KURLA STATION(E).They will cost u 20rs but u will have to sit with another 4 people and u mite be half out and half inside the auto due to congestion
