What they say
Michelin Selected
Michelin
The building has been on this Karkonosze hillside since 1899, when it opened as the Hainbergshöh resort and quickly became a retreat for industrialists, politicians and the well-heeled citizens of neighboring cities.
Tucked away
A place apart: the property is the destination.
Giant Mountains hiking trails begin right at the door, and the ski slopes of Karpacz are three kilometers away.
The rooms
Rooms in the historic building have been brought up to date, looking out toward the pine woods and the valley.
The pools
Bring a swimsuit.
A seasonal heated outdoor pool sits on the deck facing the hills, and the indoor pool has massage jets.
The spa and gym
The spa has five suites for Balinese massages and regional rituals. A fitness studio holds Matrix equipment.
Lobby Bar
Velvet armchairs flank an illuminated black marble counter serving classic cocktails and wines chosen by the sommelier.
At the table
Szyszka serves seasonal Lower Silesian dishes on an enclosed viewing terrace looking out over the Jelenia Góra Valley.
How it began

The hotel borrows Sosnówka's historic German name, Seidorf. In 1899, it welcomed city industrialists with rare luxuries like central heating and telegraph service.
