Vegans and people who care about service: Do not come near.
While the reception staff was friendly and helpful, the breakfast staff was absolutely rude and impatient. I arranged with the hotel a vegan breakfast in advance (which is also on their menu) but wasn't served one. The kitchen staff actually had no idea what vegan is. I was served an egg omelette and the breakfast waitress argued with me that vegan is vegetarian (!). I tried to explain the difference but she literally rolled her eyes and went away, complaining that "everybody wants something different", yes, in those very words. Then I was served a "vegan breakfast": a half-empty plate, basically removing whatever was not vegan from the normal plate and leaving it like that.
Management was not present at any point during our stay. After discussing the problem with the receptionist, I've sent a complaint email to them, requesting them to refund me the worth of breakfast which was encumbered in the price. They refused, falsely arguing that I was offered to be served the vegan breakfast again and refused it (at no point was I offered that, also the whole ordeal took about half an hour at which time we had to leave).
Conclusion: I paid for a breakfast which I couldn't eat, got bad service and wasn't refunded.
Not recommended.
