Had two separate one night stays here.

Stay 1: (rate 150CHF)
Even tough booking via Marriott.com (and it showing up in upcoming stays), my Gold status was not in the system for some reason. They had pre-allocated a standard room, but after asking if I was a Marriott member, I showed them my gold card on the app and they gave me a upgrade to a "deluxe" room, breakkie vouchers and internet voucher.

Room was decent sized, it was on the fourth floor but no noise issues. We had dinner in the "Mexican" restaurant, and it was o.k., tough very expensive. (everything is in Lucerne unfortunately). Breakfast was good and included full buffet for Elite members.

Stay 2: (on a Saturday) (rate 130CHF)
Again they did not have my Marriott status on the reservation. The check-in clerk remembered my name and status, and greeted me by name the moment we walked through the door. No upgrade this time, and room was small, but functional. It was a high floor room tough, which was fortunate. As on Saturdays, the Mexican restaurant changes into a nightclub and there was lots of noise. I could even notice this in our room on the high floor, tough it did not bother me to much. Was glad we didn't get a room on one of the lower floors.

Both times we parked on the street in front of the hotel, for 15CHF, which is good value. I would not hesitate to stay here again, especially for the rates I got this trip. It was great value in beautiful but overly-expensive Luzern.
