I went up to the dayrooms a few days ago to enquire about reservation for a stay mid December. There are only 2 options:
1) Make a booking there on the spot and pay in advance (either cash or cc).
2) Book by calling them on a mobile number and then paying by bank transfer to a local account. There is no option to pay by cc over the phone.
In both cases reservations are strictly non-refundable (no date change allowed either).
As others have indicated they currently seem to fully booked quite often. The girl did mention however that early December another floor will open and she expects the situation to get much better.
