Olaf and Mark's boat is the quintessential lodging in Amsterdam. So cool to be on one of the canals! We met only Mark and he was a lovely host--always checking to make sure we had what we needed, and that we were warm enough (as we were visiting in the winter)! The bed is nestled in the bow of the boat, tucked under the deck--cozy. The kitchen is new and so sophisticated--for a boat! A Nespresso coffee machine made us wonderful coffee each morning. Windows all around provide lots of light and give unique views to the canal activity on the Prinzengracht, though shades on each window give privacy when wanted. The bathroom was clean, fully tiled and with a wall radiator that kept it especially warm. It is possible to sit outside on the boat deck or at a private picnic table, but sadly it was too cold outside to use. All in all, we had a great stay at Olaf and Mark's canal boat!
