Marcel is a great host and greets you in person at check in and offers some great tips and shows you about the living spaces. The space is very clean and stylish. The bed is so comfortable you won't want to get out of it. Leave the flat to find yourself within a 5 minutes walk of Jordan, Nine Streets, and the Anne Frank House.
Note that there are 3 flights of steep stairs to climb to get to the flat, but that's normal for Amsterdam, but still something to consider if you have trouble with stairs or lots of bulky items.
If you have questions or need recommendations don't be afraid to ask Marcel.
