The house is spacious and has a great layout for families. Seaforth is a lovely suburb north of the city and ten minutes from the busy beach resort of Manly. We explored the city via the Manly ferry(a must in itself) and drove to the eastern suburbs(about 30 minutes by car) and lovely northern beaches (Avalon and Palm beach are about 20 minutes away).
Only one issue was the lack of Air-con in the house. We had two days of high temperatures which made it too hot at night.
Apart from that no issues and the owner was responsive and helpful during our stay.
