I've stayed in many different airbnbs/vrbos in Whistler, and this is the first time I've had a host message during the stay to ask if everything was going alright, or if there was anything needed. A small touch, to be sure, but definitely appreciated!
Unit came with plenty of towels, clean sheets, and plenty of pots/pans/plates/bowls for cooking and eating. Our group of 3 (originally 4 but had a drop out) stayed very comfortably. The sofa bed wasn't super comfortable for a large adult, but there was enough room for the proposed 6-person space.
The parking spot is indeed very tight, as mentioned by the host, but our Subaru Outback fit fine next to a huge pickup truck.
Great stay and location right in the marketplace really made it easy to get around. The walk to Whistler Gondola is about 7-10 minutes, and a great way to warm up for the wait in line :).
