We had a disturbing and unpleasant experience at the IBIS hotel Haarlem, It was freezing cold outside, and inside the room the heating did not work, we asked to move us to an other room, the reception told us that all rooms are the same, they closed the central room heating system for the night, finally they gave us extra blankets A NIGHTMARE !!!.
When checkout they even did not want to take responsibility,
It is the first and las time I'll book a room in IBIS Haarlem.
