I would recommend Louis’ apartment. Louis is very personable and responds quickly to questions. His apartment is very well located within walking distance to many of the attractions of Amsterdam, but away from the tourist areas. Bus and tram are within a few minutes walk. Bike rental is right across the street. There are excellent restaurants right on his block. Yam Yam, Orantes (get the lamb chops), and Brasserie De Groot were 3 that we ate at and were great. Check out a concert at the Concertbouw. It is an amazing concert hall.
The only drawback to Louis apartment are the steep stairs to the bedrooms in the basement. They are easily manageable by most people, older folks with knee issues may have a problem.
Overall, would highly recommend Louis apartment.
