We spent 3 days at Richard's place. His flat is very cosy, clean and very spacious and is also very close to downtown. We mostly walked to city center within 20-30 minutes. Supermarket is very close and there are many restaurants to eat around. Richard is very kind and friendly. He even gives you many tips about what to do in Rotterdam, where to eat or what to visit. Everything worked very well for us. I would highly recommend his place.
