First of all Marco is s great host - He lives upstairs from the apartment. The apartment is smaller than the picture might suggest but everything is first class - the shower is inspired. The location for me was over the top...I walked everywhere, museums...
Red light, Dam Square, the Jewish Quarter. Great wine shop 1/2 block away....coffee and bagels just across the bridge and a great super market right beside the Heineken Experience about 15 minute walk (or less)
