The property is very nice, beautiful and clean, the beach is just a few minutes away and you can enjoy the view just by yourself. The property manager is also a friendly and helpful person who even offered to pick me up at the bus station of Marignane. I wouldn't have expected so much kindness.
However, the property is really only something for you if you plan to stay a few days away from the crowds and if you don't necessarily need/want to go to the city of Marseille city (or if you arrive by car). I thought I could take the bus in the evening from the train station to go back to the property, but it seems there are no buses after 7 or 8 pm. It's also not very clear which public transportation you can take from Marseille to Marignane. At least it was confusing for me. But otherwise it was a nice experience.
