As a Dutchman, and someone who lived formerly in Amsterdam, I knew this location was going to be great. On top, it is a true historic Grachtenpand (Canal House) in a street that has a rich history. It feels great to bike up to this building along canals and bridges.
It being such a historic building, also has some minor trade-offs, you can hear sounds a bit better (bring earplugs) and the bathroom is a bit older and no-frills. For many of us, these trade-offs are worth the true Amsterdam experience.
Karin was very nice and flexible and does her best to accommodate all your requests. One of the bikes were stolen, so we could borrow one from the family. Overall, we were very satisfied with this one.
