We booked a Family Room to have some extra space but we were allocated a Standard Room at check-in. It took much insistence that we didn't want to be downgraded (unless we were offered a discount) and the hassle of being assigned a second Standard Room before the receptionist begrudgingly offered us a Deluxe Room instead. The Deluxe Room was very nice, but a lot of time and energy was spent going back and forth to rooms and the reception desk to get it sorted.
We picked the hotel as it was a short walk away from the Montreux Jazz Festival which would be running during our visit. We wanted to be away from the noise and chaos of the festival but still have good access and the hotel is ideally located from this perspective. However, the Casino next door was holding an all-day pool party on the day of our arrival and had loud music blaring all day (sadly not jazz!). It was impossible to relax by the hotel pool, enjoy lunch on the terrace or relax in our room due to the excessive noise. Whilst clearly not the hotel's fault, it was a scheduled event and we should have been pre-warned about this before our stay as it severely impacted our enjoyment.
Service was so-so. Some of the staff were OK, others clearly not suited for customer service roles.
Check-out wasn't much better, we were charged for Tourist Tax despite having paid it on arrival, luckily we still had the receipt. Again, was resolved but it took work to achieve.
