The most important thing for us about a ski lodge is location, and this apartment is in an amazing location. The walk to canyon lodge is no more than 5 min, and that's with kids. At this lodge is food, drinks, and importantly ski school. This base has access to green slopes for beginners but also has access to multiple lifts to get higher up in the mountain.
The apartment itself is spacious and very well stocked. It came with things that I wouldn't expect but that are very helpful when provided, things like ziplock bags, paper towels, toilet paper, shampoo/conditioner. The kitchen is also well stocked with cooking implements and some basic condiments, etc. Better stocked than the average rental for sure.
The thing that I really want to call out in my review is the kindness of the hosts. We were delayed by a big storm and arrived 2 days later than planned, and the hosts refunded for the first 2 nights that were not used. This is going above and beyond what they needed to do and what I would have expected from a VRBO unit. This amazing customer service has guaranteed that I will be renting this unit again next time I'm back at Mammoth.
