A characterful hotel at Flensburg’s Sonwik marina, with exceptional cuisine rooted in its own farm, British-inspired interiors and a team whose warmth stays with you. A rooftop pool, extensive spa and well-equipped gym complete the stay.
Returning to Das James, we were struck once again by the warmth of its people. The team’s smiles, attentiveness and infectious good humour create an atmosphere that feels personal and easy from the moment you arrive. This heartfelt hospitality is one of our strongest memories of the hotel.
The culinary experience is equally memorable, from ingredients supplied by the hotel’s own James Farm to MICHELIN-starred dining at Das Grace with chef Quirin Brundobler. British-inspired interiors, playful lamps and views across Sonwik marina give the hotel its distinctive character. Add a generous spa and opportunities to stay active, and the result is a stay we were delighted to return to.
Staying active comes naturally at Das James, with a well-equipped gym, guided training and a jogging route starting right outside the hotel.
The three-level spa brings together swimming, saunas, physiotherapy and restorative treatments.
In the restaurants, produce from James Farm creates a tangible connection between the ingredients on your plate and their origins.
Movement at Das James starts right on the doorstep, with a jogging route along the marina. Inside, the compact, well-equipped gym supports strength and cardio sessions, with a boxing ring adding a distinctive training option.

Recovery unfolds across more than 2,000 m² of spa space, arranged over three levels. Harbour views, quiet spaces and individually selected treatments make it easy to settle into a slower rhythm.

The range of treatments was a particular highlight of our stay. Alongside the main sauna area for guests aged 16 and over, the dedicated family spa gives parents and children their own space to enjoy the water and warmth together.
Food is one of the strongest reasons to visit Das James. Its own James Farm in nearby Hörup supplies eggs, dairy, cheese, meat and vegetables, connecting the hotel’s kitchens directly with the people who grow and produce their ingredients.

Afternoon tea, homemade pâtisserie and drinks at The Lion Bar add to the variety. Across the culinary offering, the quality of the ingredients and the care in their preparation stood out during our visit.





From a morning run by the marina to an individually selected spa treatment, Das James brings movement, relaxation and thoughtful dining into the same stay.
