Friedrich was a fantastic host! Exchanging keys etc was easy and well organised and the boat itself was amazing. Such a wonderful and unique experience. We did have problems with the wifi, but Friedrich did try to fix the problem.. However, since we didn't really need it, we didn't push for it, and it was not resolved - but this wasn't an issue for us and Friedrich assured us that they had not had problems before. I am certain that if we did really need the wifi, Friedrich would have fixed it straight away. The location was amazing, the boat was beautiful (and clean!) and we thoroughly enjoyed our stay.
