Colleen was friendly and very helpful regarding directions, maps and suggestions for places to go.
Her flat is centrally located and it's easy to walk about the city from there or catch a bus/taxi right outside of her door. The train is only minutes away too.
The 'guest' has his/her own bedroom with a single bed and shares the bathroom.
If I'm ever back in Sydney, I would certainly consider staying at Colleen's again. It was an enjoyable experience.
