The room is excellent, one can also use the air conditioner to heat up the place. I also found the bed mattress really comfortable, but at the same time it is pretty hard so it does not hurt your sleep form that much. Nearby there is a metro station (3 minutes walk) and also a tram station (5 min), which is connected to the Rotterdam Central Station. Overall great stay at Sandra's place, who happens to be a wonderful and lovely host.
