I stay at this property on a regular basis. This is the first time that I had an issues with a staff member. The lady at the frontdesk was refusing to accept my Swiss residence card as a form of id to check-in. Said I could only check in with a passport. I have checked in dozens of times with this id in previously. She very rude and continued to try to argue with me in front of other guests. I asked to see the manager and she walked away, to which the other check-in host profusely apologized for her behavior. The host then came back, didn't say anything and checked me in. I hope that this was a one-off, but worst experience I have had in a long time at a hotel.
