The hotel rooms are comfortable and clean. The breakfast is a buffet with many options. The staff are friendly and helpful. The reception staff member (Katia?) was particularly helpful finding a satisfactory solution to help me get to Marseille train station.
The only downside to the hotel is its location as it is inaccessible by foot from the airport. If like me your flight is delayed and you arrive after midnight you miss the free hotel shuttle and you will need to take a taxi to the hotel. Arriving late also means that you will have difficulty booking a hotel shuttle place to the airport in the morning. So if possible make sure to book your place when you make your room reservation.
The hotel is however within walking distance to the Vitrolles train station so that is a definite advantage if you need to take a train into the center of Marseille or to other cities in France.
