Fantastic location facing the Old Port next to the marina. The pier to take a boat to Chateau d'If is within minutes' walk. About 15 minutes' walk to the train station (convenient for airport shuttles). Plenty of cafes, restaurants, and shopping opportunities around. There is a metro station right next to the hotel but you can actually walk to all the major attractions.
The room was smallish but well appointed. There is a lot of reconstruction going on in Marseille at the moment so a room facing the courtyard is probably the best choice unless you don't mind being awakened by the noise of the building works outside. The air conditioner did not seem to be strong enough to cope with the outside temperatures when it got really hot. There is free wi-fi in the rooms but sometimes it failed to work.
All in all, quite suitable for a short stay.More
