I have 2 complaints:
1/ The sauna room was working but the hammam room was not. The answer I got from reception was that there was a technical problem, but on my last stay it wasn't working either. If it is always broken, I suggest to remove it from the Hotel's options (so as not to deceive customers).
2/ When booking the hotel, I looked for breakfast included. There was a note that it was a buffet (with supplement). When I went to pay the supplement, it was 27.00 CHF Swiss Francs!!! And after paying, they didn't give me an invoice, even though I insisted, they didn't give me an invoice. Only on the last day at check-out, after asking again, did they include this line on the global invoice.
