Shirley and her husband offered excellent hospitality in a very clean, beautiful space. Shirley was flexible despite us having to change our check in time, and her communication was great. The room itself is actually more like a little hotel room rather than just a private room in a house. There is a mini fridge filled with drinks, an electric kettle, a variety of snacks/mini meals, and two sets of bowls & cutlery. There's also a bathroom just off the bedroom that is quite updated and stylish.
One of the highlights of the room is the floor-to-ceiling windows and small balcony. These fill the room with light and make for a very pleasant view out onto the street (but there are blackout curtains to keep it dark in the early morning, too)! The location was also great--just a few minutes' walk to the Centraal station and a variety of restaurants and bars.
We found the room and the hosts to be superb, and I would recommend Shirley's place to anyone looking to stay in Rotterdam!
