The Spiritual Establishment Center Krelingen is a free work within the Evangelical Church of Hanover. In this case, "free work" means that it is financed by donations, not by church taxes. Otherwise, it is consciously a part of the regional church with ecumenical openness for guests and staff from free churches and in principle also Catholic and Orthodox Church (which there are hardly there).
Within the theological spectrum of the regional church, it is certainly located on the conservative border. Depending on how much one identifies with it or how open it is to look beyond one's own nose, one will feel better there or not. The people who live and work there feel good, as you can tell, depending on their own background, they are alienated or pleased.
Is it a plus or a minus to tell people what they believe in? If you are looking for a religiously neutral or spiritually indifferent conference center, you will certainly be better served by other offers within and outside the state church. There must be such. Anyone who comes here will find an evangelical work and notice it too.
If you find that good or you are willing to get involved in it for the duration of your stay, then you will encounter a beautiful chapel, a well-stocked Christian bookstore, a garden center and a very dedicated team. Service and food are more than decent, the rooms are spacious and equipped as standard, the dining and meeting rooms bright and sympathetic, the staff thoroughly friendly. It's not a hotel, but among the convention halls definitely higher standard.
The youth houses are of course simpler, but compared to other completely fine.
The study and rehabilitation work should not be an issue here, as it is about a report for visitors. But much is true here as well.
