The Host: Reinout is absolutely friendly and nice to guests; he provided assistance he could to let us stay in Amsterdam well, such as suggesting spots and things to do or not. He is full of laugh and let us feel relaxed just like at home, and provides delicious breakfasts.
The House: His house may be the best located B&B in the city, it's so close to the Amsterdam Centraal and downtown area less than 10 minutes of walk; but still keeps silent and high quality of living. It made us feel comfortable and equipped with all things we needed.
If we go back Amsterdam again, Reinout's house would be our only choice.
