Great communication, warm and friendly hosts, beautiful room, gorgeous street, and close to trams which take you all around Rotterdam.
I stayed with two friends and did not realize based on the pictures that the two beds are in the same room, but that made it very 'gezellig' (and the room is very spacious).
Jet and Frank recommended having breakfast at "Espresso Dates" on Middellandplein, and that was an absolute fantastic recommendation. I would go back here!
