If you're wanting to visit Gent, which you should coz it's a great city, then staying on one of Francis' boats will make it all the more interesting. My girlfriend and I had wanted to stay on a boat for some time now and when we saw this one we jumped at the chance.
We were not disappointed. The boat itself is a really cool space and feels totally unique. Easy to get to, with bicycles available for getting around the city. We would've used them had the weather not been subzero temperatures, instead opting for the relative warmth of our car. The boat is super clean and has all the necessary utilities for a comfortable stay. Though be warned, you will have a much more intricate understanding of your partners toilet habits after staying here, as there is no division between the toilet, kitchen and bedroom. This didn't bother us at all, it just gave us something to laugh about.
Despite not meeting Francis in person, he was very attentive, ensuring we were settled in okay and that he was contactable if we needed anything. I highly recommend staying here, especially if you're in the mood for trying something new and different.
