Sarah and Neil's place was lovely. It was the perfect size for my family, in a fantastic location. My family used the apartment to base camp out of while we were visiting family and friends in Bozeman. Sarah and Neil were very responsive, flexible, and a pleasure to meet.
One note, It is a basement apartment, so noise (foot traffic and voices) does travel from upstairs down. That being said, Sarah and Neil clearly take measures to reduce noise and the noise transfer was never an issue.
This is a great place to base camp from. It would not have worked as well for our family of four if we were eating all our meals there, however we kept it to breakfast and everything was fantastic.
