Michael's place is wonderful, and he is responsive and provided great instructions for finding the "Boat House" and checking in. The "Boat House" sits right above a stream, and it was rushing during my visit - very peaceful. The space itself is a great use of space with exceptional light.
I was able to walk to a local cafe that I have loved for years as well as one of the most romantic restaurants in Los Angeles. That said: I check the app and Lyft was readily available to those business even with the (desired) separation from the busy city. Michael has great recommendations and is friendly and engaging.
If you have never visited Topanga, I strongly recommend it and I encourage you to visit Michael's boathouse. I look forward to my next visit.
