Carole's treehouse was fantastic. My friend and I were in Portland over the eclipse and most places to stay were booked solid or outrageously expensive. Carole definitely could've charged more, but offered a very reasonable price. The treehouse was adorable and snuggly fit two 5'3'' women. The bed provided was surprisingly comfy and warm.
Carole was a great host. We had to leave super early in the morning the next day and she still stayed up late to set out our breakfast.
I'd call it similar to camping, but a bit more glamorous. My childhood dreams have been fulfilled.
