Our stay at Daan's place was amazing. It made us feel like real Amsterdam people, especially when we took our breakfast on the terrace on top of the boat ! And Daan was so nice : we got caught into traffic jams and arrived later than expected but it was no problem for him. He also checked on us during the stay :-)
The only "minus" is the double beds are not very wide, it's barely worth noticing compare to the rest of what you can get there.
