Definitely the best stay I had with AirBnB. Hans was super hospitable and extremely nice. Check in was flawless, he also told us about many activities around the city and had a coupon book ready for us. He offered us free bikes (though we preferred walking) also offered us a tour of Amsterdam and the mills (unfortunately we did not have time). Just keep in mind that the stairs are really long (4 stories up) and narrow with small steps, it would be very hard for older people and those with bad knees to climb them every time specially at check in/check out with carrying the bags (we had no issue with going up the stairs, and Hans was kind enough to offer help carrying the bags, we of course said we got them).
I highly and very strongly recommend booking with Hans, the perfect host, a great apartment, a great location and the best value for money you would spend.
