Christel is a great host, she answer very fast.
About the place, the neighborhood is normal, it is 20 minutes away from the city center and the centraal station by walking.
One bad point for us was that it is on a second floor and there is no elevator. So if you go with luggage it can be an issue. The floor in the studio is super noisy, and I found it a bit annoying for the price you pay, I think this should be fixed.
It is a good place for a weekend or so.
