I stayed at Cordula’s place for a 1 1/2 months and it was a pleasant experience as the apartment is very spacious and has all the necessary equipment to be comfortable (kitchen, bathroom, home office , small Gym, etc).
Although I enjoyed my time in the apartment, it is located in a very family neighborhood, so it’s a noisy due to children and the upstairs neighbors.
You can get to the Rotterdam central station with just 1 tram or a 20 min walk from the apartment.
