From the airport : bus nr. 98 ( every 20 minutes) go off the bus stop: Gambetta. From there it takes about 5 min walkes.
Continue on the Promenade des Anglais until the Hotel Negresco, than turn into the Rue de Rivoli, straight on, second corner on your right: there you are !
From the Central Station: take the rue Berlioz, walk straight on, after 15 min. walk you arrived at your flat.
By car: Next parking place: Massena ( beside the Museum Massena, 20 m from the apartment). You also can try to find a parking place in the street ( free during the night), but you may need patience and the French way of driving (not getting nervous when the whole world around you seems honking ).
