We loved being at Kim's appartment. It's spatious, well organised, with nice furnitures, comfortable and where everything works perfectly. You have place to organise your own things and really feel 'at home'. It's in a living neighborhood and yet the appartment has a calm and quiet ambiance. It's also very well located in the city: we can do a 3-day trip and see a lot of Rotterdam even by foot only.
In short, you have only good surprises when you arrive at Kim's appartment. She's a very good host!
