Even if we had some difficulties to find the boat and the fact that there wasn't any toilet paper, we had a really nice experience at Petra's place.
We were a little disappointed when we found out that we had to pay extra for the breakfast, which we thought it was included.
The way to the boat is difficult to find : you have to enter a really little street that looks like the entrance of a parking lot. Fortunately Petra helped us to find the way there and was really helpful.
The price is a bit expensive for what you get but it is a good opportunity to spend your holiday on a boat.
