My friend and I had a wonderful, relaxing stay at Rahmat and Ralph's home. The rooftop room and bathroom were perfectly clean and the whole area restful and beautifully designed. They were very helpful and made it easy to explore Rotterdam as well as relax in the room with WiFi, tea, coffee etc. One of the best stays we have had with Airbnb and we very much hope we can return someday. Thank you for being such friendly and warm hosts, R&R!
