My husband and I stayed here on the last leg of our honeymoon in May 2011. The hotel is in the most perfect location. Right on the beach - a small, gorgeous beach that appeared to be popular with the locals. It's a nice 10 minute walk to the port, which means at night it's quiet. We stayed in the suite on the 1st floor and it was gorgeous. Huge room, huge terrace, perfect view. It felt incredibly luxurious and romantic.
Now for the cons - the staff at the hotel are not the friendliest people. Most of them did not speak English, which I understand we were in France, but at an international hotel there should at least be 1 person who speaks English. And as many reviews state below, they were rather cold and off-putting. They were not helpful when we had questions about restaurants or activities at all. This was the most frustrating thing. We asked one of the receptionists where we could rent kayaks, which is a very popular thing to do in Cassis, and the man just shrugged his shoulders and said he had no idea.
Also, the breakfasts are rather underwhelming. Nothing really appealing besides fresh baguettes and fruit. Although the view from the terrace where breakfast is served makes up for that.
All this being said, I would still choose to deal with the abysmal staff and disappointing breakfasts again if it meant I could stay in a room with this incredible view and location. I think it's worth putting up with bad service for what was otherwise a pretty great experience.

Stayed here for two nights in early Oct 2010. It was a very pleasant surprise and a great way to end our vacation. The view is magnificent - rocky cliffs, beaches, fishing boats, blue water, sunrise sparkling over the sea. We had a third floor room in the middle with a balcony. The room was not large but we loved the sound, feel and smell of the sea breezes and sitting on the balcony with a glass of wine.
The staff were friendly. The breakfast content was typical/continental but it was nice to enjoy it on the canopied deck out front of the hotel.
The view of the cliffs across the way is very nice (bring binoculars), but for a real thrill drive to the top of the cliffs and stand a few feet from the edge of the cliff (no railings) and the view of Cassis below and the expanse of the sea if truly breathtaking.

Before you get in your room everythings seems to be perfect: A stylish website, nice pictures, perfect location next to the bay of Cassis, good prices, nice terrasse with an amazing view of the Côte d'Azur…what can you expect more?
Unfortunatly when you get into your room, real life welcomes you.
It is not really what you expected: The bathroom smells strange, not renovated, old style, on the bacony the long chair was broken and we could't use, the rest of the funitures looked a-like. The bed was very small for two, the fridge was old and ugly.
The waitress in the restaurant in the morning were more busy with talking to each other than taking care of their guest: We waited to the bread and on the next table the piguins came to eat the rest of the bread of other guests.

All in all: We got an older room without discount and the hotel sells itself better than it is and for that, it is too expensive.
We also informed the friendly lady at the reception about that and she really gave the impression that she will take care of it which is a plus. Hopefully she will do so otherwise it's not a big joy to return.

We were the in September and got an parking spot (payed) on the parking place very easily but in the high season you should come very early or late. The city with the harbor can be reached within 5 minutues which is very conveniend.

I can't understand how this hotel is so far down the ranks for cassis. It's location is incredible and it is a very good hotel too. We had a small room but the view was to die for we could lie on the bed and watch the sun rise above the sea and towering cliffs. Service was excellent staff very helpful. Hotel is nicely done up. Breakfast is adequate - it's nice to find a hotel in France where breakfast is included. Overall can't recommend this enough.
