We spend two nights in the apartment with four adults (grandparents) and a baby and had enough room. With four adults it is good for a short city trip. If you want to stay longer, it might get a little crowded with the bathroom situation. But just parents with children or couples will have enough room for a longer stay.
The area around the market is really nice with a market, little shops, restaurants and supermarkets. We liked it even better then the city center. You can walk downtown within 25 minutes or take public transport.
J was always available and answered all our questions. He also offers bicycles with child seats for rent.
We traveled by car. It’s easy to find a parking spot in front of the house, but it’s pricey. So it might be worth checking for alternative P&R garages.
Even with many restaurants around the street, it was very quiet at night.
The perfect mix for an Amsterdam trip.
