Hotel Spa

Has a pool

Has thermal facilities

5 treatment rooms

The Royal Yacht, centrally placed in St Helier, is one of the island's oldest hotels, dating from the 1820s. Spa Sirène is a serene bonus in a stylish place to stay. This luxury hotel spa is in a basement, but the pool, heat experiences and dramatic decor make up for the lack of sea views. Spa Sirène offers a range of Phytomer treatments; this marine-based product range is made in the nearby French town of St Malo.

Our Spa Spy Review

First impressions

The Royal Yacht is a very modern building in the centre of St Helier, just next to the harbour.  The hotel is light and bright throughout; even the basement spa is cleverly lit to pull the natural light in. There are sea and beach canvases throughout the hotel and, rather romantically, Spa Sirène is named after the French word for mermaid. Each of the treatment rooms are named after mermaids from international folklore.

What's on offer?

The reception at Spa Sirène is bright and white and has plenty of products on display.

The spotlessly-clean changing rooms are well equipped with wooden benches and padded stools in front of a huge floor-to-ceiling mirror. The Phytomer products are great to try out while enjoying your spa day. A glass door leads through to five showers, all equipped with Aromatherapy Associates shampoo, conditioner and body wash.

Inside the tall lockers you'll find a white waffle robe, white fluffy towel and slippers. If you need an extra towel for your hair, or to dry off mid-way through your day, there are lots towels available on shelves in the changing rooms.

The 12-metre pool area is the centre-piece of the spa. The sea theme continues with sail cloth draped across the ceiling and at the far end of the pool is a bubbling vitality pool and three swan pipes. There are pairs of wicker chairs around the edge of the pool to sit and chill out, but they will also be used by day spa guests to eat their lunch. There's also a table with iced lemon water and tea making facilities.

Just off the pool area, the relaxation room hosts three heated loungers which are used by those enjoying the pool space as well as those in need of a post treatment chill-out. The loungers are screened off, so there's an element of privacy here. There are no reading lights or magazines, but you can watch the changing chakra coloured lights.

The thermal facilities are lined around the edge of the pool. There's a glass-fronted Swedish sauna, a eucalyptus steam room, and a salt therapy steam room. If you're feeling brave try the cold bucket shower. There are also two mosaic-tiled foot baths.

Children under 16 are not allowed in Spa Sirène, so your swim should be fairly undisturbed.

Tell us about the treatments

I had the Smooth Sailing Facial (£95, 75 minutes).

Elena, my therapist, collected me from the pool area and took me to the treatment room. She briefly left the room while I got comfortable on the treatment bed.

Designed in collaboration with an osteopath, the treatment began with a very relaxing back massage. Elena then mixed powdered mud with water and spread a line of the concoction along some foil and placed it behind me, as I lay back it coated the skin along my spine and bubbled away. Elena explained the magnesium and calcium in the mud bubbled when it came in contact with water, which is supposed to be very detoxifying.

Elena began work on my face by cleansing and toning before applying a lip exfoliant which softens fine lines around the mouth. She then smoothed a peeling exfoliator onto my face.

After removing the exfoliant, Elena began a dry massage using the palm of her hands to stimulate pressure points on my neck, face and scalp. She then turned my head to the sides and massaged around my ears.

Next Elena used her finger tips to manipulate pressure points on my face, focusing on the crown of my head, eyebrows, temples, and cheekbones. Using facial oil, she then used the Phytomer roller (imagine a very dinky plastic paint roller) to massage the contours of my face, and her hands to massage my décolletage and arms.

Using a brush Elena applied a paraffin-based face mask and placed a piece of gauze on top. While the mask worked its magic I chose to have a foot massage (clients are given the choice of a foot, hand or scalp massage) which was blissful.

Elena removed the mask and applied eye and face moisturizer and a serum. She then sat me up and removed the mud mask on my back.

Spa Sirène has a host of nautical inspired treatments including the Sea Sculpting wrap and the Rough Seas exfoliating treatment. There are also options for men and mums-to-be.

Food facts

Day spa guests can eat poolside in their robes. The spa menu is short but delicious and light; with choices such as sushi and sashimi, salads and sandwiches.

Other food options at the Royal Yacht include the very buzzy Café Zephyr which serves Asian food with bold flavours and the fine dining restaurant Sirocco which has views of the harbour.  The Grill is for carnivore purists - they only serve steak and wine.

We loved / We didn't love

We loved

Our brilliant therapist Elena, who is a firm favourite amoung the regulars.

The duck-egg blue bowl sinks in the changing rooms – very cute.

We didn’t love

The lack of a dedicated post-treatment relaxation room.

The water temperature in the hydrotherapy bed could have been warmer, we got a bit chilly.

The lack of shower doors. The lack of privacy is fine when you're rinsing off chlorine, but not if you want to have a proper wash.

Who do you think would like it?

Anyone who likes to feel they're in the middle of the action. The spa is in downtown St Helier, Café Zephyr was packed and The Royal Yacht Hotel has its own night club called the Drift. Soak up the city vibe.

Anyone who wants to spa without kids. Hotel guests with children will be given free passes for Aqua Splash (a nearby leisure centre pool) so parents can spa in peace and kids can enjoy splashing around in their own pool.

What bubble rating did you give this spa?

We gave Spa Sirène a Good Spa Guide Rating of 4 Bubbles. It is a beautiful and stylish spa with great treatments and good customer service. However, it does not have a dedicated post treatment relaxation room which is a bit disappointing.

Super Spy visited in July 2014 and awarded it 4 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.
