Guillermo's place is in an older but centrally located apartment, that he keeps very clean. The room wasn't particularly big, but perfect for my needs.
Sadly, he wasn't in town when I stayed so I didn't get to experience the paella, but did get a house to myself for great value!
It's an older house and comes with its quirks, but you can't beat the value for money - and being only a stone's throw away from the beautiful Rushcutters Bay park.
