Great hosts! Communication with Eric was easy and Jeanette gave us a really thorough introduction to the Rothor along with lots of amazing tips for Rotterdam: activities, good local restaurants (we went to one of the recommended restaurants and did not regret it), cheap nearby parking, you name it...
The interior of the boat was super cozy and nothing was amiss. Also, the location was outstanding. Many of the top things to see in Rotterdam were merely a stone's throw away. If you don't get lost on the way while looking at the cube house like we did, it takes no more than 5 minutes to walk to the famous market hall. If we happen to visit Rotterdam again in the future, we will definitely try to stay on the Rothor again.
PS: Make sure to check out Eric's picture album of the history of the boat and the different stages of progress of his restoration work. Also, they have a cat that is very cute and friendly!
