Philip is a nice host, who can give you some advice if you are exploring the city and the country in general.
I can recommend the appartement, since its very near to the city centre and still a quiet area to stay. There were no long rides home after walking around in the centre, since you just have to take the Metro and you will be home quick. I had relaxing days there, i could feel at home and chill in my part of the appartement.
I would definetly stay there again, if i'll come back to Amsterdam. Beautiful city, anyway...
