I can confirm without any hesitation that, both Kim is a great host as well as her apartment is a perfect place to stay for a weekend (or longer) in Rotterdam. Kim was waiting for our arrival, she briefly gave us all necessary information, maps,etc. The room looked exactly as it does on the pictures, the area was well located (by tram around 10 minutes from the city center- night coming back by taxi only 9 euro:)), we had no problems with agreeing on key return and no time limits. Kim also brought us some treats for a breakfast. All in all- I fully recommend.
