We rented the condo to attend a graduation in Erie, PA and we were 16 with a mix of different ages. From the outside the condo looks small, but it's pretty spacious on the inside. Most of the rooms have full baths, except one of the bedrooms has a half bath. The upstairs has the 2 "bedrooms", which are basically a large room with multiple beds and a bed in a large corridor leading to that room. Those rooms can fit about 6-8 people pretty comfortably and there is 1 full bath there. Then there are 2 bedrooms on the main level with full baths each, and 2 bedrooms on the lower level, one with a full bath and one with a half bath.
We didn't spend a lot of time in the condo, but when we were there it was enjoyable. The fire pit was nice to sit around at night.
There was a hitch with the ski lift because we were not aware you had to pay for it by getting a wrist band at the club house below, where all the other activities are. So, we rode it down because we saw that it was running, but we got yelled at by the attendant at the bottom and they wouldn't let us get back up. We had to go to the hotel and have them drive us back up with a shuttle. Other than that, we had a good time and it served it's purpose.
