Kim was a great host, very welcoming and showed us her beautiful apartment which she designed herself. She had more than enough things to make you feel at home. Kitchen was full of little things so you don't need to buy anything other than your food.
The neighbourhood is dead centre in a very trendy neighbourhood..and quiet. The bedroom is at the back of the apartment so totally quiet and peaceful.
Rotterdam is a very down to earth, very friendly, peaceful, clean cut city (architecture modern!) a welcome contrast to the chaos of Amsterdam - you can easily cycle everywhere and if you're feeling adventurous you can cycle to Delft and D
The Hague - above all, stay at Kim's place.. 10/10!
