Travelling from Nice to the Apartment using Public Transport.
The best way is to take a short bus ride from Nice airport to the local train station. From here you catch a train to Saint Raphael and from Saint Raphael you catch a bus to La Foux (Geant Supermarket) 500 yards from the apartment.
When returning to Nice using public transport it might prove less stressful to travel the day before you are due to fly and check into one of the hotels just in front of the airport and have an evening in Nice. This would allow you to book a morning flight out of Nice and avoid the worry of missing the plane because of a delay in travelling to the airport.
Ensure that you can manage your luggage and that it is easy to wheel, as there is a small walk from the apartment to the bus stop.
