【明報專訊】Last week I was recording music in a treehouse in LA, which I found through AirBnb.com, a website where people put their houses and apartments online as holiday lets. I love Air BnB - it's a great resource for places to stay when you don't want to book a hotel, and every booking leads to a quirky adventure. People tend to be as unique as their homes, so if you choose the right place, you're guaranteed to like its owner. I booked this particular treehouse because my producer Dave is visiting from London, and we wanted a quiet place to write songs. It's owned by a sassy actress called Hope, who has a vast collection of cool books and guitars.
