Very nice but small apartment (one room, 25qm) at Singel (perfect location, 10 minute walk from Amsterdam Centraal train station) in the basement of an old house. The apartment has three beds (one double bed, one sofa). The kitchen is small but sufficient. The small bathroom (with shower) is located beneath the double bed. The apartment is best for a couple or a couple with one child (I stayed there with my mum and my daughter). The furniture and the tableware (e.g., dishes) are super nice and authentic. Erik and Ernestine have small children as well. You can hear them in the morning. This was OK for me (I have a small son as well), but my mum got awake early. Checkout was at 11h.
