Marieke is a great host. Unfortunately we didn't get to meet, but she arranged for us to pick up and drop off the keys in an easy way. She even arranged for welcome drink at the local coffee shop where we picked up the keys - just what we needed!
Marieke was quick to respond to our messages, and very helpful when it came to giving advice for activities and restaurants etc. for two Amsterdam novices. The apartment is a gem, personal and cosy, yet stylish. There's public transportation within walking distance, which for example takes you directly to the central station as well as the museum area.
We would stay at Marieke's place again, no doubt :)
