We truly enjoyed our stay in Manly. The location of the AirBnB is unbeatable. The Made Comfy team was very slow to respond via AirBnB but easy to reach directly. Note they are very strict on check in/out times so we ended up booking an extra night to avoid a 10am check out.
The space was small but very efficient. I would also note this place would feel tight for 4 adults, but a family of four fit well.
Our largest complaint was the lack of screens on the windows that caused lots of bugs on hot days and excessive dust and allergies. The flat is also very warm on hot days. Bear in mind for longer stays (such as our) we ended up purchasing many little things for the home (trash bags, soap, toilet paper, toiletries, etc).
Overall, I would happily book this AirBnB again and highly recommend Manly as a great jumping off point for families visiting Sydney.
