I've spent 4 days at Kamil and Dorota house. It was quite nice. The room is a little bit dark, but there was everything I need: good table and chair, decent wi-fi, spacious bed, kettle to prepare tea. Shared kitchen (it's also a living room) is cosy. I prepared several meals there. Also there is 2 beautiful cats in the house. During my stay it was interesting to talk to Kamil and Dorota. I get a lot of useful info about Rotterdam. The house located 20 minutes away from Rotterdam center. There is several small shops nearby.
