Translation of potency in German

We decided to fly directly to Hanoi and booked a flight for the same day. Before we left we still had some time to visit the War Remnants Museum. One could see the former headquarters of the South.
We continued to the entrance of Angkor Wat. They told us that if we would wait until after five o'clock we could enter with next day's ticket and still see the sunset. We waited and entered at five.
At the third or fourth guesthouse we finally took a room. Of course the hot water would not work, and luckily we were upgraded to a terrific, huge room with balcony and garden. It was a very charming place.
