Frank's houseboat is amazing. The whole boat was renovated only last year, and it's obvious. The space inside is very modern feeling, and even with limited square footage it feels like you have everything you need.
Frank, and his family, are great. When we were walking up the dock after arriving in Amsterdam Frank and his young son ran out to greet us. Frank took our bags and helped us get them into the rental space at the front of the boat, then showed us around, talked to us a bit, and gave restaurant suggestions. When we would go out during the day, he and his family and neighbors would be hanging out on the boat, enjoying the nice weather, and wish us a good day. Just very pleasant people.
Amsterdam was my favorite stop on our recent European expedition that also included London and Paris, and Frank and his boat played no small part in that. If I get to return I will hope to stay here again.
