Jet's place is amazing. Its interior looks like a hotel. The bathroom is very clean, big, and equipped with everything you need (shampoo, shower gel, conditioner, hairdryer, towel, etc.). I stayed there with 3 of my friends (total 4 people) and the space is definitely big enough even for 4 people. The sofa bed surprisingly is as comfortable as the bed. The location is also great: quiet neighborhood and walking distance from Rotterdam Centraal station. I would definitely stay here again if I visit Rotterdam again.
