We stayed there for three weeks and had a great time. The apartment is really spacious and equipped with everything needed for a longterm stay: e.g. all kinds of toiletries, washing powder, spices, dishwashing detergent, towels and so forth. There are plenty of cosy sofas to relax. However, a few things could be fixed or replaced to make it even more convenient.
Although we never met Gillian she was always reachable and responded promptly to all of our questions and requests. We arrived in the evening and were pleasantly surprized to find some bread, butter, fruits and even a bottle of white wine in the apartment. That gave us a feeling of beeing very welcome.
There are plenty of shops and restaurants within walking distance. Even the city center is only a 20 to 30 minutes walk away. Despite the central location the environment of the apartment is rather quiet.
If staying in Sydney, we recommend Gillians place.
