Yes! Exchanged in July 2017. It was decent and we enjoyed our stay. It was our first week of almost a month in Switzerland. Although It's not my absolute favorite part of Switzerland -- that would be Bernese Oberland area, been there 2x now -- there's plenty of good stuff to do for a week, and it's in a sweet little town with train access. I booked it to piggyback with another exchange I'd already confirmed + 2 private rentals, we'd decided not to rent a car at all this trip, and it fit perfectly. They include a transportation card for train and bus (and cable car if I recall correctly) access to various local-ish destinations in the area, so we had several lovely hikes, plus went to Glacier 3000 which was fabulous (take sunglasses!). I wouldn't turn it down if the timing works for you.
