I stayed at the Kahler during Summer 2010, as being a patient at the Mayo Clinic. The front desk staff were extremely friendly/helpful. They had a fan that was available for use as I can't sleep without one. Although the cleanliness of the room was great, the location of this hotel is what makes it worth it. You can access the Mayo Clinic without stepping foot outside. (There is an underground hallway that takes you from the hotel to the Mayo Clinic.) There is also a place to eat as well as a Starbucks :) located in the main lobby. It is also within walking distance to numerous other great restaurants, a Barnes & Noble, and cute shops. In addition, a shuttle is available to come and bring you to the Mall of America. Like I said the cleanliness of the room isn't great however with the location of this hotel can't be beat! There is also a shuttle that picks you up and drops you off at the airport, which is very helpful. This is the only place I would stay if I was to be going to be going to the Mayo Clinic again. There are numerous other hotels you can stay at in the area, however none are as close to the Mayo Clinic and are nearly as convenient. In addition, there is a great fitness center located at the top floor with new workout machines, weights, and a pool. Plenty of vending machines with easy access too!
