Coco was incredibly communicative and helpful before, during, and after our stay (when we accidentally left a coat in a closet).
The place was spacious and looked exactly like the pictures. The beds were very comfortable and the curtains blocked out the light quite well. The place is very well-equipped even for an extended stay - you've got everything you need to have a lazy day at home or cook a meal. We particularly enjoyed the big TV in the living room and the tons of storage space! The location is super-convenient for travel within Rotterdam as well as to other cities via the central station nearby.
There are plenty of restaurants, bars, and cafes in the area too. Great stay!
