Absolutely recommended!
I spent 3 nights at the place and had a great time. Kim is a really great host. She suggested many places to visit in Rotterdam and lend me the card to use for travelling during the stay. There is also a welcoming breakfast on the first day.
The place is very clean and the bed is very comfy. You have everything you need in the kitchen. Location is perfect too as you have tram and metro right in front of the place. There are also mcdonald and a supermarket only one minute walk away.
