I personally like the host, Gijs is a nice guy. The location of the apartment is perfect. But I wouldn't recommend that apartment.
Because:
1. The shower is very difficult to use (either water too hot or too cold)
2.The Bed is very noisy (every turn makes a squeaky noise)
3.The library was very dusty and not "clean".
4.The pictures are not even close to reality.
But all these points can be fixed easily (I hope this review gives a push to get this Airbnb apartment up to expectations)
