I was overall happy with my stay at the Fairmont FKL, with one very important exception (listed under cons below).
Pros: Close to the gondola, has a nice spa and decent gym. Mostly friendly staff. Spacious rooms. Okay level of cleanliness.
Cons: Rooms do NOT look like they do in the hotel photos, they are dated and in need of a renovation. Rooms also have no AC which was almost unbearable during hot summer days. The worst con of them all is, however, that I was contacted after my stay because I had not paid a 10 dollar (!) fee for a yoga class I took the same day I checked out of the hotel. I mistakenly thought the hotel had my credit card for incidentals so I just asked them to charge it to that card. A few weeks later I get an email saying that they have been trying to contact me to pay the 10 (yes 10) dollars for a communal yoga class that is offered everyday regardless of how many participants there are. In other words, the yoga teacher would have had to be paid irrespective of whether I had attended the class or not.I wrote back saying that of course we will pay the 10 dollars but I find it appalling that they would hound me over 10 dollars when I paid OVER 2500 dollars for a four night stay. Despite the overall decent experience, this left a bitter taste and I will not be staying at a Fairmont again.
