German Bar-B-Que night & a house on hill

Yesterday my advisor invited everyone in our group to his house for Bar-B-Que (Grill). We all went there in the evening from the university in cars and reached his house. It was in the North of the city. The house was located diagonally along the side of a hill. After parking the cars, we went up the stairs to his house. There the professor handed us some things to be taken to the Grill location which was located higher on the hill. So we climbed more stairs uphill and found a magnificent place there. It was a beautiful lawn with a small swimming pool and flowers all around. After some minutes, the professor came and said, "why have you stopped here; i asked you to go up". And at that moment we looked up, hust to find another storey up the hill. So we again climbed the stairs to find another lawn with a wooden cabin, a shed with lots and lots of fire-wood and a tree-house for the kids. This was finally the end of professor's house. It was sorrounded on one side by an iron fence and beyond were the woods.

Admiring the four storey house, we sat and started the Grill. It was a very cold period going on (even in July), so after eating, we sat under a shed and placed the fire near us, throwing wood every once a while into it. It is here that one German commented on my German speaking. He said that foreigners normally speak German in their own accent (close to their mother-tongue), but i speak without any accent and pronounce it very accurately. Anyways, they surprised me by sitting very late, although it was no holiday tomorrow. When they finally got up at 12:30 am, i was sure nobody would reach on time in the morning. But they are Germans after all. Everbody was on time, except of course. . .

I did catch a cold that lasted many days.
