Jan's place is great! I traveled with my boyfriend and two other friends. With three bedrooms and a large open living space, we had more than enough room and could have easily slept another two or three people. The place was very clean and had lovely views of the canals on both sides. It is a bit out of the city center, but its an easy walk (under 5 minutes) to the tram that takes you directly into the center in about 15 minutes. Being outside the center was perfect for us, as it was a bit quieter (we slept with our balcony door open each night with little too no noise from the street). Overall, a great place for couples, friends, or a family to stay in Amsterdam!
