We had great communications with Jenna. The studio is above the garage area and is warm and cosy.
Just as Angus and others have noted the stairway is tight and may not be suited for those with walking difficulties or if you have heavy luggage.
The location is easy to find and for us, it was an easy 10 minute from Central Station. (from the time we picked our bags at the airport, onto the train and the walk to Angus' place was less than 40mins).
Also it is not far (about 20 mins) to the Sydney Cricket Ground / Allianz Stadium.
A quick walk to the station and you can catch a train to Town Hall station, for the shops, Darling Harbour, Circular Quay Station for The Rocks, harbour Ferries, Sydney Harbour and of course, the Opera House precinct.
Food is no problem with a Coles and a Woolworths supermarkets both nearby (in opposite directions). There are plenty of restaurant in the Redfern /Surry Hills areas.
If you want to cook in the unit, everything is there for you to do that, including a full size (Miele) oven. The fridge is small and is what we call a bar fridge but is perfect for a short stay.
