Our stay at Leentje's was really good. The location is perfect, close to everything in the city centre, and the place is lovely -although be careful with the stairs! The view of the cathedral from one of the windows is really nice, but if you are a light sleeper the bells may wake you up in the morning.
The communication with Leentje was great from the beginning and we didn't have any issues with arrival or departure.
We would definitely recommend this place!
