Siem welcomed us and made sure we knew everything about the boat. He left us some eggs, bread and cheese and made us feel very welcome. The boat is a real cosy place and also very private. We rented bikes from 'Starbikes' close to the central station which was a good a cheap solution. It takes 20 min. to get to the center of the city and the bike ride there is very beautiful.
We had no problems whatsoever so if we come to Amsterdam again we will definately rent Siems boat once again.
I highly recommend the woonboot to every couple who wants to come to Amsterdam.
