Unfortunately we didn't have opportunity to meet Marijke, but her friend who hosted us was very helpful and reachable.
The room isn't very big, perfect for two people, even for longer stay, but as we were a group of 3 it was just enough for a 3-night weekend.
The location is really good - 3 minutes walk to the train station - you can be at Central Station in less than 15-20 minutes.
The neighbour is really calm and quiet. We loved the bench in front of the apartment.
The room was clean and tidy. Only one thing missing was some space to unpack the luggage - sort of wardrobe or shelf would be nice.
All in all I highly recommend staying in this room.
