We had a great stay at Alexander's flat in Manly. Excellent location, just a short walk form the ferry (we caught a plane, train then ferry to Sydney from interstate late one evening) and close to everything in Manly.
The apartment is spacious and comfortable with everything you need, comfy bed and we slept well. It was surprisingly quiet and we got to hear the kookaburra's nearby in the morning which we liked.
There is a great cafe 'Roast Office' literally two doors up the street, we went there each day for breakfast and they have good coffee and teapots of black tea as well.
Communication with Alexander was good and check in/out was easy. An excellent place to stay!
