Petra was always really nice and reactive by mail.
The boat is really perfectly located in Amsterdam, surroundings are beautiful, in the quiet and charming district of Plantage, everything you can dream of is at a walking distance.
We loved living on this beautiful boat for a few days, we felt like dutch sailors...with all the comfort in addition! Heating is working well, beds are comfortable (though only single beds) and the living room is really nice.
Martin was a really helpful guardian, always there, nice and available.
I would strongly recommend if you want to live something really special in Amsterdam!
