We've spent a long weekend in Amsterdam (Friday-Monday) and I must say we were very happy with Leo's place. The location is really nice, the neighborhood is calm, but at the same time very close to the city center and Centraal train station (you can get there by a free ferry in just a couple of minutes). Leo was really helpful and well-prepared, asked all the questions and was really nice. He also has an adorable cat, which was an additional attraction for us :) The flat is quite small, but very clean and with everything that you need, so it's a great option for a weekend or other short stay!
