Maria's place is very near to the Haarlemmerplein station and even Centraal Station (only 3-4 stops with bus). And plus, her nearby environment is so Dutch-typical.
Maria herself is like a mom to her guests, also to me and my sister during our stay. She always concerns about us, was always willing to hear our experiences of the day and providing suggestions. Last but not least, her willingness to provide us early breakfast in our last day was so helpful, and such memorable to us.
I recommend her as your host while you're in Amsterdam!
