Brita and Reinhard are wonderful, generous people. Brita thought of everything a weary traveler would like to have when checking in at the end of a long trip. Snacks, fresh fruit, even a small bottle of wine were exactly the things that say, "welcome and enjoy."
They are citizens of the world and have many experiences to share and are looking to hear and learn from others. They interact if you want to but also give you plenty of privacy. A great trip made even better by these kind people.
