I've stayed at three different apartments/bed and breakfasts in Amsterdam over the last three years. For a single person or a couple this would be my favorite place so far.

There are two different rooms and you definitely want to try to get the room with the canal view (I think). The location is just about two steps away from the chaos, but you probably want to be two steps away from the chaos so that it's quiet when you get back at night (it was always nice and quiet when I was sleeping). Price includes a continental breakfast brought to your room so that's also good. If I get to come back to Amsterdam I'd definitely try to come back to this place.
