My girlfriend and I had 3 wonderful days in Amsterdam in Marcel apartment.
The apartment is small but beautiful, very clean and with everything you need. The terrace is awesome.
Marcel is a very nice and friendly guy, and a wonderful host. He gave us a lot of information and left in the fridge wine, beer and coke.
The neighborhood is beautiful, very quiet and close to the centre. You can use the bicycles that Marcel provided, it's amazing to visit amsterdam by bikes!
