Vittorio, although you gave some positive remarks, I found your review rather negative. If you should have read the advertisement better, you should have known that you rented a room (is so much cheaper) and not the appartment (is twice as much). Nowhere in Amsterdam you can have a whole appartment for the price you paid. I have 2 advertisements: 1 for one room, and 1 for the whole appartment. How come you think you could chill in the living room and eat there???? Such a shame you give this kind of feedback.
Then the distance: like I told you there are many city centres: the Jordaan is only 10 minutes by bike and tram from me, the Central Station and the ferries and the Dam: only 16 minutes by tram, the Rembrandtpark: 5 minutes walk, Vondelpark: 20 minutes walk, 10 minutes cycling, etc.
You now make it seem as if the centre is 30 minutes away....Peccato!
