Matthijs is a generous & helpful host. He could teach a class for travelers coming to Amsterdam for the first time - the information he provides is comprehensive on a wide range of topics. He was extremely quick to respond to messages - especially during our stay when I had an issue with my suitcase.
The apartment is exactly like the photos & description. It's on a side street but may get some noise from people walking to busy areas so it was recommended to sleep with the windows closed. Not sure if it would feel stuffy if it's warm weather but it worked great for us. The windows cancelled out any noise from the street. Steps to the apt are steep as expected but he was there to help with our bags. The shower is a bit small but worked well enough for my 6'2" boyfriend.
The included breakfast was wonderful and a the shop was a short 5 minute walk from the apt.
