Staying at Hetty's place was great! My friend and I stayed 3 nights. Very centrally located and 2 tram stops are right out the door. Plenty of cute shops and restaurants in the area. We did not meet Hetty but her son kindly picked us up from the airport late at night and she kindly messaged us. Food is provided for breakfast which is great for running out the door to explore the city. I would definitely stay at Hetty's place again when returning to Amsterdam!
