The experience on the boat was absolutely different to any experience I have had before. The Isabella is a small boat, but pretty good to spend a few weeks enjoying the lake and the city. I could met good people, have fun and enjoy the amazing view from the harbor. Wake up and have breakfast slowly in front of the lake and the big buildings of Chicago... it was one of my favorites moments in this city.
The idea of staying in a boat in Chicago sounds cool already. But staying at The Isabella, that's when you see that all the other stuff are boring. Karl is an awesome, easy going guy who made it all to make me feel at home. He's not at the boat all day, so he let you do the things at your time and he's fair with the tasks.
Also the harbor is a good place to meet new people and Karl has a lot of friends who are always around.
