Maartens place was quite far from amsterdam central ( which is what we wanted) in a beautiful wooded area full of trees and birds. Not once did we feel in danger while walking around at night. The metro station is only a short walk from his place, and takes 20mins to get to the centre. Even though the location is far away from amsterdam central, the fantastic public transportation makes life so easy.
The apartment itself was only ok. The place was very dusty and incredibly cluttered. For the price you are paying for it, you would expect it to have a certain level of cleanliness, which fell short of. It really could do with a coat or two of paint and a bit more TLC. The place had many culinary toys to play with, but unfortunately there was no oven or microwave so if you plan to use this place for cooking your own meals I would certainly take this into consideration.
I am certainly not trying to put anybody off renting this place, as it really is in a great location for anyone not into the busy city. I am just suggesting a bit more care goes into the apartment.
