Excellent private, friendly and comfortable stay.
In Jeff's place you get what you pay for. You have your own studio type room where you can do everything without going out. Nevertheless, you can enjoy the common spaces and share with the other guests too.
The place is a big guest house with almost 20 rooms. It is in a central location with the main street in less than 100m where all the supermarkets, restaurants, and stores are. Also, Coogee Beach is at a 20-25min walk (2km), and the light rail to the city centre and UNSW is only at 600m. It's a pretty well connected place.
Jeff and the staff are very friendly and were always in touch. I had a problem with some bugs and Jeff helped me mitigate it fast.
I would recommend it to my friends and would come back again.
