Sally was a great host and very responsive. She even met us at 6am for the check in.
The bed was extremely comfortable and we slept very well. The kitchen was also immaculate and had everything we needed for cooking.
The building also has a laundrette which was ideal.
The location is perfect and we loved it for its central location and easy access to museums, coffee/eating places, supermarkets, etc.
It's also 3 min walk to the Cook & Philip Park Swimming pool (50m pool) which offers day rates for AU$ 7. The flat is also ideal for jogging in the Botanic Gardens. Both of which we did daily.
Note that the flat is not double-glazed (as is the case with the entire building) so you will hear some traffic noise from the road. But it was not too much and with earplugs I slept very well.
We will certainly stay again when in Sydney.
