Hotel Sonneck runs seminars and conferences for groups of 10 to 80 people in nine meeting rooms, with 60 bedrooms, a restaurant and a pool under the same roof. The family-run hotel stands on its own in the Knüll nature park at Rengshausen, part of Knüllwald in northern Hesse, about 6 km from the A7 motorway between Kassel and Fulda.
Seminars and company events
The house is built around meetings. Its largest room, An der Kastanie, measures 160 square meters and seats 80 in rows, 70 at parliamentary tables, 60 in a circle or 39 in a U-shape. It can be split into three: a main room of 116 square meters and two small rooms of 22 square meters each. Five further rooms take 6 to 40 people, and several small spaces serve as breakout rooms for group work.
Almost all seminar rooms open directly onto the garden and a sun terrace, so breaks can move outside. Fiber-optic internet runs through the building. Three day-package levels are offered, from a standard day to a full business day, and special weekend conditions are quoted on request. Extras such as a welcome coffee, unlimited drinks, extra breakout rooms or a microphone system can be added.
For the evening, the hotel arranges group activities on request, such as a torchlit walk or a campfire. Jogging routes start at the door.
Rooms and capacities
All rooms carry the names of trees. Am Zwetschgenbaum, at 82 square meters, seats up to 40 in rows and 25 in a U-shape. Am Kirschbaum, at 68 square meters, takes 30 in rows. An der Eiche, at 51 square meters, and An der Buche, at 48 square meters, each take 20 in rows and 15 in a U-shape. Am Apfelbaum, Am Birnbaum, An der Linde and Am Haselnussbaum are small rooms of 19 to 24 square meters for teams of four to ten. The full table by layout is on the hotel's site.
Accommodation
The hotel has 60 bedrooms in several categories, so most seminar groups can sleep on site and start the next morning without travel. Conference guests can use the wellness area, with a swimming pool, saunas and a fitness room, at no extra charge.
Catering
The Restaurant Sonnenblatt cooks fresh regional food with seasonal dishes, including vegetarian, vegan and gluten-free options, and looks out over the nature park. It is open daily. In the evening, a bar with an open fireplace and a lounge give groups a place to meet after the sessions.
History and setting
Sonneck is a family-run house in a quiet, isolated spot in the Knüll hills, which the hotel describes as the middle of Germany. It holds GreenSign Level 4 certification for sustainable operation and has charging points for electric cars in the parking area.
Getting there
The address is Zu den einzelnen Bäumen 13, 34593 Knüllwald-Rengshausen. By road, the A7 is 6 km away, which puts Kassel and Fulda within easy reach. For rail travel, Kassel-Wilhelmshöhe is the main long-distance station in the region; ask the hotel about the last leg to the house.
