Lori and Scott have done up a small space above their garage into an absolute treasure of a place that feels like a FULL home away from your own home! They have appointed The Loft with just about everything you can think of and the personal touch and attention to detail relative to amenities is just super. Starting from providing a 'starter' pack (yogurt, half and half, granola/cereal, pasta and pasta sauce) to all the addons you find in a home (5 kinds of cooking oil, a variety of spices/condiments, top-end toiletries, bicycles, other outdoor sport activity equipment, grill for your use, board games, etc.), everything is extremely well thought out. Frankly, this is the BEST appointed Airbnb, we have stayed in.
The space is ideal for a couple but can easily accommodate a family with a couple of younger kids for a few days. We were there at the end of August and so weather wise we were in the low 70's/upper 40's. Between keeping some of the windows open at some times of the day and the room A/C, we were just fine. The bedding is super comfortable and you can assure yourself of a good night's sleep. Do keep in mind, the shower is not in a separate room. It sort of a part of the sleeping area with a shower curtain providing privacy.
Their welcome book, The Bee, has some good information on local area facilities and food options. We tried The Blackbird and had their flatbread and also went to the Wild Crumb for a few pastries/croissants. Both places were very good. We tried a couple of other places in town - Ted's Montana Grill and a Mongolian BBQ place in north Bozeman (no liquor served here). We would definitely recommend them.
If you enjoy hiking, do pursue the M Hike. Takes a couple of hours, but is a nice hike with a great view from the top.
