I highly recommend a stay at Hendrick and Betty's apartment. It is in a historical building on a quiet street but close to the tram link, a supermarket, bakers and restaurants too. You can easily and pleasantly walk into Rotterdam in 30 minutes.
Betty provided us with a map of the city and there are lots of guide books and info sheets to help you discover about Rotterdam in the flat. The flat has a double bedroom and a good sofa bed in the sitting room which my 6' 3'' son found very comfortable. There is a sweet balcony and a small garden although we didn't use them due to the time of year. Betty provided us with lots of food for breakfast including bread, waffles, yoghurt, cheese and salami. There was wine, beer and fruit juice and also chocolate. It was a real feast. Betty even offered to wash and dry our crockery each morning. A fantastic service. Don't worry if you forget something I will almost guarantee that Betty has thought of it for you. There is a full range of toiletries including deodorant, cotton buds, body lotion etc.
The apartment was perfect for a stay in Rotterdam and felt very relaxed and homely. I would highly recommend a stay here.
