The prices you mention are per person per night right ?
No, it says:
Atrium Room
€57.50 per room per night (With breakfast)
Total costs: €115.00 (2 Pers.)
Executive Room
€79.50 per room per night (With breakfast)
Total costs: €159.00 (2 Pers.)
@bela: is the executive room worth the price difference?
I think not too much, our room was beautiful and comfortable, but didn't look like as they described on their website.
As I can see from your pics from last year, the rooms are almost similar, I will go for the cheaper Atrium room this year.
