Booking with Peter and Ralf you will get a great, beautifully decorated apartment stretching over two floors with a lot of amenities. The rather steep stairs are to be considered though if you have a small child or are not well on foot.
What makes it even more special is the hospitality of your hosts. Friendly, flexible (we checked in too late, sorry!) and full of good advice - you can't wish for nicer hosts!
The apartment is very close to a tram station from where you can directly reach the center of rotterdam. A bakery, multiple fruit vendors, two supermarkets and more in the direct vicinity were a big plus for us as well.
