We just stayed at the bunkhouse for the past week. there were 6 of us and the space worked well! My husband, son and I slept in the loft. my sister-in-law stayed in the airstream and my in-laws stayed in the bedroom. We were worried about sharing the bathroom through the bedroom but it wasn't a problem.
Chris is a fantastic host! The house had everything we could possibly need. This was my best Air BNB experience to date!
