Alsik Hotel & Spa

On Sønderborg’s waterfront near Alsion and Sønderborg Castle, this spa hotel sits within easy walking distance of the city center, Solitude Beach and Flensburg Fjord. Sonderborg Airport (SGD) is about 7.7 km away. Pet-friendly on request and known for sea-view rooms, it’s a sleek Nordic escape.

190 rooms, including 21 junior suites and suites, with Scandinavian interiors that lean hygge—natural materials and colourful accents. More than 90% of rooms offer sea views. Rooms feature heated floors, air conditioning, flat-screen TVs and tablets, mini fridges, coffee/tea makers, safes and desks. The Alsik Nordisk Spa covers about 4,500 m² over four floors with an impressive hot-and-cold bathing landscape.

Stand-outs include the large Nordic spa, indoor and outdoor pools, sauna and a 24-hour fitness center. There’s also a hair salon, concierge and a program of massages, facials and body treatments. Wake up to sea-view mornings and step straight out for coastal walks.

A conference center (4,004 sq ft / 372 m²) and 10 meeting rooms support events and banquets. Other business-friendly touches: 24-hour front desk, concierge, laundry/dry cleaning, complimentary wireless internet and lobby newspapers.

Three on-site restaurants—one is Syttende—offer regional, typically Nordic dishes crafted under chef Jesper Koch’s influence. There’s also a bar/lounge, a coffee shop/café with snacks, and limited room service for late bites.
