Penny's place was sparking clean and very well situated - the area is full of trendy coffee shops and restaurants and it takes ~5 minutes walk to Kings Cross (with train + bus connections across all Sydney) The check-in was smooth and Penny did not hesitate to let me stay longer on my last day too.
The bed was super comfortable and the shower was the best I have encountered so far - the temperature and pressure were just amazing! The bathroom is separate from the room (literally next door) but I found this good as I could leave my stuff in bathroom too.
