due to the immediate need for an apartment and needing it to be in the center, I've had to find something immediate, out of approaching many people frank was the only one who answered pretty much immediately and was always communicating in order to get everything done. even with the super late booking (night), frank followed his promise to arrive early morning (from Den Hague) to welcome into the apartment and putting the bag. after some quick arrangements while went for some coffee, got into the apartment which is as described with small modifications (more sofa room)
the house was very welcoming and filled with real living atmosphere, even the refrigerator was full :)
there was an espresso machine which is very important to me, and the internet was working perfect. it was raining so using the balcony was not so practical, however the view from the balcony is relaxing.
the location is perfect for people who are not worried to walk a little, as it's in the center to everything.. 10-15 minutes walk from everything.
as a host frank was pretty much amazing, there was not much need for tour assistance etc, however he was always available to answer questions.
to sum things up, if you need a place for a short business meeting in Amsterdam or longer stay for a vacation, the place is pretty much perfect. (but don't expect a mansion)
as far as I could notice the only disadvantage is the church in the nearby area which is the only noise making (every 30 minutes) in the area, but you get used to it after few times.

I would definitely recommend the apartment and frank as a host.
