We enjoyed our stay at Melinda's place in Surry Hills / Redfern. Check in and out was simple, we didn't meet Melinda but she was easily available and we had no problems during the stay.
As described, the house is better inside than out - the location between a pub and garage was fine for us but may not be for everyone. Inside we had plenty of space and the yard at the rear was good for breakfast.
The space had a lived in feel, suited to young groups. Great neighbourhood bars, restaurants, galleries etc. and if in a big group we'd definitely consider staying again.
