Stayed the week before Christmas with 3 adults and 4 teens... plenty of room to spread out, and beds for all (with one to spare)!
Location was great for us - we valeted our skis at Park City Mountain, and therefore were able to walk comfortably to/from when hitting the slopes - about a 10 minute walk. A city bus stop (and bus service is free in Park City!) is also located right outside the unit on Park Avenue, which we used for trips downtown but could also be used for the ski resorts. Grocery store, drug store, liquor store, and a 7-Eleven all within a reasonable walking distance - so no need for a car (a big money saver for a group of seven).
The pros: location, lots of space, fully equipped kitchen, washer/dryer in unit, and very comfortable for a big group. The semi-pros: unit is a bit dated (but you're not paying for the Ritz) and not so sound-proof. The cons: no code given for the hot tub area (it may not have been operating), and the fireplace was perplexing to operate.
Overall, we found this unit a very good value. The combination of price, location, and sizeable accommodation was perfect for us!
