Martijn is a great host, he is very kind and welcoming. The apartment is beautiful, cozy and comes with a small bathroom. So it has everything you need and you even get separate access to the Apartment, so you don't wake up others when you are coming hone late. I was staying at Martijn's Place with my girlfriend and we were very happy with the Apartment and its Location.
Martijn even had bikes for us (Free of Charme) which was great to discover the city in the typical dutch Style! :)
We definetly can recommend a stay at Martijn's place.
