Petra was great host :)
The apartment is nice but small in near of centrum. You need 20-30 min of walking to get to the Dom, which is center of town. We love to walk but someone who doesn't can take a tram ( TIcket is 5€). We recommend you to buy online tickets on getyourguide because it made our trip even better. We took ticket for canal cruise, heineken, volendam and marken, zoo and rent a bike ( one bike for one day - 13€).
In aparment was little bit cold because we couldn't turn up the heating by ourselfs but if you ask Petra, she will made that for you.
