The Amstel botel is a large boat, that now serves as a hotel. It is docked at the NDSM Wharf, one of the cultural hotspots along the developing North shore of the river IJ.
To get there, you can use the (free) NDSM ferry. Outside the operation hours of the ferry, there is a free shuttle bus that brings you to the (also free, always operational) Buiksloterweg ferry.
Since July 2015 there are large letters on the roof, making the name BOTEL. They have rooms inside that can be booked.
