The only aspect of the hotel I can complement is its location: Azur is a reasonably short walk from the train station, the Vieux Port, and nightlife in the Cours Julien neighborhood. However, unless you're staying in Marseille very briefly and location is all that matters to you, I would recommend staying elsewhere. (Now onto the negatives.) First, we were immediately taken aback by the smell emanating from the bathroom when we got up to our room -- it smelled overwhelmingly of mold. Second, entrance to the room require navigating our way through three locked doors, using three old and rickety keys that we had a VERY hard time getting to work. (It wasn't pleasant coming back to the hotel after a late night of dinner/drinks and barely being able to get back into our room -- plus, the front desk closes at midnight so there was no one around). Third, we got back to the room late to find that the heating system did not work, and the room was quite cold (even colder the next morning when we woke up). Finally, when we came down to check out and pay the next morning, the man working at the front desk refused to let us pay with a card, instead requesting that we pay in cash. We would have stayed longer arguing with him but we were already running late for a train we wanted to catch, so we just gave up and paid in cash. I found the whole payment episode sketchy, since the guy made no claim that the card machines weren’t working.
