Staying at The Green Room was truly delightful. Hendrik was very quick to respond prior to arrival and was very flexible with our timing. We didn't get to meet him as he was then working, but Betty welcomed us warmly. (giving us a tour of the room, instructions on how to use the appliances and a few pointers on things we could get up to on our stay, from the large collection of Rotterdam travel guides/books within the apartment). The room was really nice, cosy and well decorated, and the breakfast provided was more than expected (enough to take some as snacks on the go!). On the last day, we were able to leave our bags behind for the day and pick them up before going to the airport. Highly recommended!
