Also there were reunions before, like Vienna and Cologne, this one was the first time that so many could make it.
That's how we hosted 6 people in our flat. In order of arrival :
Michal, Yvonne and Ann-Ca, Matthieu, Thibault and Martin.
We had a lot of fun during those 36 hours since it was summer and exactly in the highlights of Ulm summer activities.
