Sarah is a great host, she is very prompt and helpful in her comms and response to messages. Her apartment is spotlessly clean, and the bedroom and bed are very comfortable. The apartment is in a good location, within an easy walk to the Manly wharf, beach and a wide choice of cafes, pubs and restaurants. The only downside for me, because I was driving, is that parking around Sarah's place can be hard to find; I think this is true for much of the suburb of Manly and obviously is not an issue if you are visiting by ferry or other transport that does not require parking.
I would definitely stay at Sarah's place again (and would just allow an extra 15 mins to find a parking spot!)
