I have just come back today from Sun Valley. The location is fantastic and the apartment grand. The real disappointment is the staff, who just don't have a clue about anything. They lost our deposit check, made up a silly excuse, and asked us if we had paid for the local tax, even though it is the first thing you have to pay for when you get there!!! Other than that, everything was perfect. Very close to the slopes, the couple of bars, pool and the Spar.
