This is a comfortable, roomy and unusual apartment that would be difficult to beat for exploring Rotterdam by foot or Metro. The main space is two stories high, and the bathroom is roomy and the kitchen just fine for simple cooking or heating up food from a market. Curtains can be opened or closed to bring in our shut out light. There's an occasional mosquito but Bertie has spray there and I don't think I ever got bitten. If anyone is extremely sensitive to street noise or unused to an urban environment, this is not the apartment for them. That said, both myself and my guests had no problem sleeping through the night. I certainly hope to return to this place, and to bring family or friends, so that is the highest recommendations I can think of. It was such a pleasure to walk out and be in the middle of central Rotterdam, with lots of excellent food options and many friendly people.
