Martine is an excellent host, I was meeting my girlfriend in Amsterdam, as I live in Scotland and she in Switzerland, and we encountered problems such as my flight getting postponed to the next day, and having a marathon on the day that we were leaving; in every instance Martine helped us out and informed us. Her apartment is amazing, very well decorated and with all the amenities that you would need. The narrow 4 flights of stairs can seem daunting at first, but you get used to it. Martine has a guest manual which explains how to get around and where to go to, absolutely fantastic.
