My family (2 adults, 2 kids) was in Whistler for a 4-day ski vacation and this townhouse was a great home base for us.
It has all the creature comforts you'd expect (internet, TV, laundry, full kitchen) and is in a great location, close to slopes and the village but away from the noise. Unfortunately, we couldn't use the free Whistler shuttle to get around since the union was on strike (not the owner/manager's fault), so it was especially convenient that everything was within a 5-7 minute drive. As one review said, yes there are 2 sets of stairs to get to the actual living quarters, but this was not an issue at all for our family. Also note, the washer and dryer are not "full size" but still a great amenity to have when one has wet ski gloves/socks.
