Spa Sirène

The petit and stylish Spa Sirène can be found in the basement of The Royal Yacht, one of Jersey’s oldest and most sociable hotels. The pools and facilities, huge changing rooms stocked with Aromatherapy Associates products, and warm and friendly staff make it a popular place to recharge. Around the 12-metre swimming pool you’ll find a large hydropool, a comfy glass fronted sauna, foot spas, two steam rooms, and a cosy and quiet relaxation room with warm mosaic tepidarium beds.

Our Spa Spy review

First impressions

First Impressions

The Royal Yacht, centrally placed in St Helier, is actually one of the island's oldest hotels, dating from the 1820s. The old part of the hotel is linked to a newer, tall building with glass panels, decking and curved balconies overlooking the harbour. The ground floor has an invitingly busy and buzzy terrace bar and restaurant. The hotel is large but modern, with clever lighting and water walls marrying the old and the new.

Spa Sirène is a serene bonus in this stylish place to stay. The spa is in a basement, but the pool, heat experiences and dramatic decor make up for the lack of sea views.

On offer

What's on offer?

The spa reception area is bright and white with natural stone colours, flowers, and products on display.

The changing rooms are impressive for a relatively small hotel spa, with touches of turquoise in the design. They are spacious, light and clean with huge wooden lockers with keys, two private changing cubicles and wooden benches. The four large showers have Aromatherapy Associates shampoo, conditioner and body wash; the fact that they have no doors might be off-putting to some.

The vanity area has four pale blue stools neatly tucked under a wooden dressing table with hairdryers, cotton pads and plenty of Phytomer products, including facial cleanser and toner. There is a swimsuit drier – with some laundry bags on a bench on our visit – and plenty of clean fresh towels on shelves.

The pool area is atmospherically lit, with a glistening light lattice on the far wall. White sails float just below the ceiling and frosted glass seals off the gym that runs down one side. The 12-metre swimming pool has blue tiles and underwater lighting, graduated steps at one end, and is pleasantly cool. A rectangular hydro-pool has water beds and back-massaging jets, and is big enough to seat a sociable group of six.

Around the pool are chairs, recliners and tables with spa menus for ordering lunch or pool-side smoothies. Tall wicker seats are curved like ice-cream cones: great for privacy, although too dark for us to read a book. No children under 16 are allowed, so this keeps the pool as a spa pool, rather than your normal hotel pool.

Doors lead off the pool to a small aromatherapy steam room, a salt therapy steam room, and a glass-fronted Swedish sauna, all of which were at good temperatures during our visit. You can dip your toes into one of the two mosaic foot-baths, brace yourself beneath the bucket shower, or rinse off in the experience shower.

A small quiet area to one side of the pool has three ceramic heated tepidarium beds separated by screens and lit with colour-changing lights.

The post-treatment relaxation room has beds divided by shimmering fabrics for privacy. Silhouettes of trees adorn one wall, where the lighting gently cycles through a range of colours.

Tell us about the treatments

We had the Time to Unwind treatment (135 minutes, £175). 

Nagila, my therapist, met me by the pool and led me to a large treatment room (the rooms are all named after mermaids) with lilac accents in the lighting and a shimmering curtain. We started with a sea-salt scrub all over my body. I washed this off in the shower -- feeling my skin smoother already -- then placed myself face down on the treatment bed.

Nagila gave me a fiercely intense back, neck and shoulder massage. She used long, flowing strokes up and down my spine, and around my hips. It felt like she was on a personal mission to unknot every glitch in my tense shoulders. There wasn't a knot that she didn't tackle.

I turned over and, while I was sitting up on the bed, Nagila coated my back in warm mud, designed to soothe and to withdraw impurities. I lay back down on the bed and Nagila turned her attention to the facial part of the treatment. This included a seaweed mask that warmed up while it was on my skin, lots of divine facial massage and a "youth" mask (always welcome). While the masks worked away, so did Nagila, treating me to a hand and arm, leg and foot, then a scalp massage. At the end, there was no bit of me that went unloved.

The time went by in a trice. After removing the mud with warm flannels, Nagila took me to the post-treatment relaxation room. Here I could drift off with some mint tea and a real sense of well-being.

Spa Sirène offers treatments using marine brand Phytomer, made in nearby St Malo in Brittany, and Aromatherapy Associates. Some have marine-themed titles: the Smooth Sailing facial and Sea Sculpting body wrap for women, or The Captain's Choice body treatment for men. The spa also offers manicures and pedicures, specific treatments for mums-to-be, and alternative treatments such as reflexology and Indian head massage.

Food facts

Food Facts

You can order lunch from a healthy spa menu and eat it by the pool in your robe. Try chicken pitta, falafel wrap, sushi and sashimi, or quinoa salad, for example, alongside a range of inventive smoothies and juices including coconut water. My beetroot salad with goat's cheese was tasty, and the green juice featuring spinach, cucumber and celery made me feel positively virtuous.

Perhaps it's not surprising the spa food is so good given the quality of the food in the rest of the hotel. The Sirocco restaurant offers classical cooking and fine dining with local ingredients and vegetarian options. Our steak Diane flambéed at the table was theatrical and delicious in equal measures. Sirocco is smart informal but, if you fancy something even more relaxed, try Zephyr on the ground floor, or The Grill for steaks.

We loved / we didn't love

We loved / we didn't love

We loved

Our treatment: The massage felt very uplifting and the products were fragrant and soothing.

The Spa Sirène staff: They were very present in the spa, collecting towels and making sure all the guests were okay.

We didn't love

The total semi-darkness: Reading lights in the pool area would make it a more pleasant space to sit, sip smoothies and read before or after your treatment.

What bubble rating did you give this spa?

We awarded Spa Sirène a Good Spa Guide Bubble Rating of 5 Bubbles. The spa was spotless, all the facilities were in good working order and my treatment top-notch. Although small, the spa maintains a feeling of friendly intimacy. The staff, food and pool area make it an indulgent hotel spa experience.

Single Spy visited in October 2018 and awarded it 5 Bubbles.

"fantastic treatments that puts clients at ease and leave them feeling relaxed rejuvenated. The spa setting and facilities are superb and add to the overall feeling of being pampered in a calm unhurried manner. Wonderful service that I both prior to my wedding and prior to the birth of my first child and I will definitely be a return customer in the near future."
