Holtby, who has an English father and German mother, says playing in Israel has been a "privilege."
"The trip was special for us," he said. "We already knew about the history of Israel and the Holocaust, but to experience it here makes us think about so many things. It's a privilege to play here."
Germany and Israel's relationship on and off the pitch has grown immeasurably since the Jewish state attained full UEFA membership status in 1994.
In 2008, the DFB launched a program which saw German national teams of all ages travel to Israel on a yearly basis to play friendly games and take part in an educational program.
The following year it signed a "Memorandum of Understanding" with the Israel Football Association which has seen the countries work together on the development of referees, coaches and young players.
Earlier this week, players visited the Hadassah Neurim Youth Aliyah Village where they posed for pictures and spoke to some of the 400 students who attend the local school.
Germany, which last won the U21 competition in 2009, failed to progress from its group on this occasion, but the lessons learned off the field have given its players a new sense of perspective on life.
"We are very happy to be in Israel," said Eintracht Frankfurt midfielder Sebastian Rode. "We learned a lot about the country when we were here in March, a few months ago.
"We've experienced great hospitality and the country is beautiful from what we've seen. When you look at it on the television we see different pictures, but it's great to be here."
Israel's hosting of the competition has been a topic of controversy, with campaign groups and some famous names within football calling for a boycott of the tournament due to the country's treatment of the Palestinians.
A petition raised by pro-Palestinian campaign group, Red Card Israeli Racism, attracted over 8,000 signatures, while Archbishop Desmond Tutu was one of a whole host of names who signed an open letter in The Guardian newspaper in Britain in May.
But according to the German players, this tournament has given Israel the opportunity to show a different side of itself on the international stage.
"It's a great opportunity for Israel to show another face of the country and not just the politics and what you see on the television," said Lasogga.
"When you see the conflict, it's not nice pictures. But when you come here you get a completely different picture of Israel, and this tournament can give people a completely new perspective.
"It was very important to come here before the tournament. It was nice to see Israel and it showed us some of the country and showed us how the people are here.
"All the places and people have been so friendly, helping us and making us welcome."
