Elmar met us at the apartment after providing excellent directions from Centraal Station and gave us a detailed tour, including instructions for using the washing machine. He also gave us restaurant, grocery and touring recommendations. He responded quickly to email questions and was a wonderful host.
The apartment was spacious, clean and well-equipped - we cooked at least one family meal and found everything that we needed. It is well-served by Amsterdam's extensive tram service, having a stop for one line right in front of the building, with others in easy walking distance.
We were unfortunately not able to take advantage of the bikes, having one child with a broken arm, but in different circumstances, the bikes would have been an additional plus, since cycling in Amsterdam looks like an experience not to be missed!
Altogether, a wonderful spot -dankjewel, Elmar!
