We had a wonderful time at Studio Mazzo. The studio was very clean. Niels also gave us nice tips, especially very good restaurants recommendations. We were able to rent a bike very closed to the apartment at "Frederic", for a reasonnable price. The Studio is, to my mind, located in the best area of Amsterdam : 1. it is beautiful, 2. you are not far away from the center and from the main station as well. I definitvely recommend Studio Mazzo and will come back to this place if I visit Amsterdam again. This is a place that feels like home.
