A good place on the quiet street yet close to everything (10 min. walk to Voldenpark and from their to museums, about 25 minutes walk or 7 tram stops to Central Station, a little less to the Dam Square, 2.5 blocks from the bus station with direct bus connection to the airport).
The apartment is in the mansard (which is really the 4th floor). The stairs looked intimidating at first (Andre must know this, he didn't let us carry out suitcases upstairs, he insisted on doing it himself which we really appreciated) but in a couple of days you get used to them so they become "part of experience". Once you are upstairs, it's a pretty spacious room (better than most hotel rooms) with the high vaulted ceiling and large window (that opens), beds, a small flat screen TV, a large dresser a table with chairs; there is a bathroom with shower and a little "kitchenette" with tiny fridge, sink, microwave, coffeemaker, electric kettle and some plates, cups and silverware - not enough to prepare a family dinner (who would be doing that on vacation?) but enough to put together a quick breakfast (a supermarket is 2 blocks away).
Andre was very helpful, the notes that he left on the table (his favorite restaurants, markets and stores, places to see, small towns to go, transportation and museum tips and a few maps) were just as helpful in planning our time and finding our ways around town as this was our first visit to Amsterdam.
So, overall, a very good value in the very good location - if, of course, you don't mind the stairs.
