I loved this place. It is located within the city walls, has lovely garden, swimming pool, Jacuzzi, sauna and steam room.

There is parking on site for 12 Euro per night. The breakfast buffet was good but a bit pricey at 14 Euro. You can take breakfast on the terrace, which is lovely.

The rooms are huge, the beds comfy and even the shower only bathroom were large. Everything was clean and tidy.

Nice touches included bathrobes and slippers provided to go to the pool area.

The staff were very friendly and helpful. They gave us great dining recommendations.

I liked the City and there was a running of the bull’s festival during our stay, which was an added bonus.

When I was looking for a hotel halfway between Barcelona and Nice, I was at first struck by the paucity of 'interesting' choices. So I decided to try Aigues Mortes, which I loved as a place, but had only previously visited for lunch. The Mazarin seemed to be a secret, but sounded OK, so I took a chance.
It's down a very narrow lane (they all are in Aigues Mortes), and unloading the luggage was a bit of a trial. But inside it was a treat. Wonderful stone staircases, and huge, bright room, overlooking the garden, and a tiny restaurant decorated in a style that even Elton John might find a tad over-baroque.
On further enquiry, we found out that until recently it had been a 'gay-only' hotel, which explained the architectural taste and squeaky-cleanliness.
There's a large undercover pool (and a 'dark room' in the cellar...harrumph), and a green garden shaded by immense plane-trees.
The staff, once they accept that you're heterosexual, are charming and helpful, and breakfast is desultory but willing. We didn't eat in the hotel (there are too many other choices in town), but the menu looked good. There's a nice Indian restaurant just around the corner...or there was...I can't see chicken Vindaloo catching on in deepest France.
Parking is a bugger but available (and you need it in A.M), and I'd recommend driving a small car....not an immense gas-guzzler like mine.
To sum up, I can't wait to go back. My Find of The Year.

Stayed for one night. Nice central location within the wall of Aigues Mortes with an underground car park.

The entrance to the car park was a little tricky (probably because of a large 4x4 parked adjacent to the door on our visit) but bags of room once inside.

Very friendly and helpful staff.

We opted to eat there in the evening. The food choices were limited and not necessarily to our taste but of a high quality if overpriced.

Great pool for a refreshing swim.

Room was a good size (with air conditioning) if a little under furnished.

We have stayed in other hotels within the walls of Aigues Mortes and this is the best hotel so far.

We would (and probably will) return but would eat out side of the hotel in the evening having first walked round the centre of the town and picked and booked a restaurant for the meal.

Aigues-Mortes is one of those magical Provençal villages that begs exploring. We wanted to book something within close proximity of the Camargue salt flats, among other attractions, and happened upon many positive reviews of Villa Mazarin. We spent three nights and the place did not disappoint. The hotel's history is fascinating and its rooms are generous in size and beautifully appointed. We'll certainly go back. The breakfast is worth the extra euro. Our only suggestion is to step up the quality of the coffee—the brew on offer was pretty forgettable. And what's morning without good java, especially in France?
