We had a great stay at Patricia's house. The rooms are beautifully decorated and we felt immediately at home. The nice christmas tree was a big bonus! We didn't met Patricia, but the communication was very clear. She left a nice note, a book about Rotterdam and some cake at our arrival.
We spent three days with 4 (including two children of 3 and 6 yo). The boys slept in one room: Patricia rearranged the room so that there was room for an extra mattress. The beds are comfortable, the living room is spacious and very cosy.
The house is a bit outside the centre, but very easy to reach by tram. It's a quiet and nice neighbourhood.
