My son and I stayed at the Westside Nest for about two weeks in January, and we had a wonderful time. Tess and Ryan are terrific hosts. It's easy to understand why they have the Super Host rating. They are attentive without being intrusive. They respected our distance in this COVID era, but stayed in touch. They even let us know when they were going to be away briefly, and they had a back-up in case anything came up (which it never did).
The Nest is very well appointed, very clean and very convenient for what we needed. It worked perfectly for us. I was working remotely part of the time, so having a strong internet connection was vital. That worked very well. We mostly cooked in. The kitchen is spacious and well-equipped. There are multiple grocery stores nearby. We got take-out a few times. The Nest is very convenient (maybe 5 min drive) for picking up food from the many restaurants downtown. Our main leisure activity was downhill skiing. The Nest is very convenient for the route down to Big Sky.
This was our first experience with a somewhat "longer term" Air BNB rental, and it worked out beautifully. We would highly recommend the Nest, whether it's for a long stay or a short one.
