From the airport: take the Tisseo airport shuttle that will take you to Toulouse and get off at the stop "Compans cafarelli" then you will remain 300 meters on foot.
From the station: it will take you 20 minutes walk if the heart tells you, otherwise you can take the metro and get off at the stop "capitol" and you will have 6 minutes on foot, otherwise you have the opportunity to go down to the 'stop "Cafarelli Compans" right next to the house.
