Just outside this window is Terminal 1 of Frankfurt airport. The window glass is pretty thick and there's no way to open it, so not much noise came inside. Fresh air neither... The hotel is great, breakfast buffet was one of the best I've ever had. Better than this: there were so many pillows on the bed, even I was unable to use them all...I love pillows :-)
Just to continue the series: this is the Radisson SAS in Cottbus. Unfortunately I just spent the night here on the travel through, got no time to discover the city...
My hotel was remarkable green with many palm trees and bushes. So it was in strong contrast with the dead volcanic ground around. It was sort of an oasis... The center of this oasis was a very large swimming pool area. It looked especially great at night because of the underwater illumination.
