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.

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 buzzy terrace bar and restaurant. The hotel is large -- they issue you with a map on arrival -- but modern, with clever lighting and water walls.

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 lockers, two private changing cubicles and wooden benches. The four large showers have Aromatherapy Associates shampoo, conditioner and body lotion. The vanity area has four pale blue stools neatly tucked into a wooden dressing table with hairdryers, cotton pads, and plenty of Phytomer products, including cleanser and moisturiser. 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 and graduated steps at one end; it is pleasantly cool. At the other end of the pool are three powerful swan jets to ease your shoulder muscles. A rectangular hydro-pool has water beds and back-massaging jets, and is big enough to seat a sociable group of six.

At the opposite end of the room are chairs, recliners and tables with spa menus for ordering lunch or pool-side smoothies. Around the edges are tall wicker seats curved like ice-cream cones, great for privacy, although too dark for us to read a book. The spa is only open to those having treatments to the value of £75 or above, and 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 would seat four; all 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 relaxation room to one side of the pool has three green stone tepidarium beds -- one hot, one warm, one cooler -- 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 Oligomer Ocean Journey (75 minutes, £90). Spa Sirène has worked with their skincare partner Phytomer for ten years, and this treatment, unique to Spa Sirène, is a celebration of that partnership.

Nagila, my therapist, met me by the pool and led me to a large, white treatment room (the rooms are all named after mermaids) with lilac accents in the lighting.

We started with a sea-salt scrub exfoliation with my feet in warm water, which felt very welcoming. Nagila surrounded me with a spritz of aroma, gave an introductory little neck massage, then let me get comfortable on the treatment bed, face down.

Nagila gave me a proper body brush to stimulate my circulation, over the backs of my legs and along my back. She followed this with massage using long, flowing strokes. Unusually, she massaged both of my legs at the same time. I had been a little sceptical that the treatment would, as it claimed, ‘simulate the rolling sea’ but it certainly felt that way: rhythmic, repetitive and soothing. Nagila also chased down the tension in my knotty shoulders.

I turned onto my front so Nagila could brush the front of my legs and my arms, following this with more massage. She included lots of work on my feet, finding the reflexology points, and also on my tense neck. I was beginning to drift but a quick application of tonic to my skin, which was chilly, woke me up. We ended with a deliciously soothing scalp massage which, as far as I was concerned, could have gone on all day.

Nagila took me to the post-treatment relaxation room where I did drift off after some mint tea. The Oligomer Ocean Journey is a lovely, restful treatment, and I had a real sense of wellbeing.

Spa Sirène offers treatments using marine brand Phytomer, made in nearby St Malo in Brittany, and Aromatherapy Associates. Some have marine-themed titles: the Calm Seas 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 simple spa menu and eat it by the pool in your robe. Try salads or sandwiches, as well as a range of inventive smoothies and juices. My chicken sandwich with avocado mayonnaise was fresh and delicious, as was my friend's smoked salmon.

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 has three AA rosettes; our asparagus soup with truffle from the open kitchen was quite delightful. 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

Our treatment: The massage felt very nurturing 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?

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 was top-notch. Although small, the spa maintains a feeling of friendly intimacy and numbers are carefully managed so that it never feels crowded. The staff, food and pool area make it an indulgent hotel spa experience.

Single Spy visited in November 2017 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."
