Because of its history, I have never heard anybody bragging that Germany was his/her Number #1 holiday destination. Personally, I studied German at school for 5 years, which allowed me to go to Germany several times between 1991 and 2004. I had really good times in Kaiserslautern, in Bayern, in Freiburg and eventually in Stuttgart.
During those visits, the Germans that I met were always very friendly and extremely hospitable. Professionally, I worked with German partners for 5 years and they too were very professional and surprise, surprise, quite respectful of the deadlines.
