Our stay at Kim's was wonderful. Everything was pristine, and the entrance way is full of information booklets about the city.
We arrived to check in and Kim's mother was there to let us in and show us the ropes. The room itself is more spacious than the photographs can show, and the shared kitchen is great if you want to make a quick meal rather than going out. However, there is no oven or toaster, so we made pasta and salad, the ingredients for which were purchased just across the street at Jumbo.
A few fast food spots are within 50 paces of the front entrance, as is the metro and trams to get you all over. Including Rotterdam Centraal, the Euromast, Markthal, and the cube houses.
