Jan was an amazing host. He made us feel just like if we were home, he was very nice. Jan offered us the coffee every morning, helped us find our way through the town. He always gave us very helpful information about the city. He was also very convenient for the check-in and the check-out.
The room was clean just like the entire apartment. It was perfect for the three of us. It is situated near the center (about 10-15min walk). So you don't need to take the bus or the tramway to visit Amsterdam.
I would definitely recommend Jan's room!
