Staying at Marion's was great, she was really friendly and helpful. She has a book of food and activity recommendations from previous guests, which really helps you decide where to go and what to do.
Her place is very well located - 10 minutes walk from the beach and 10-20 minutes walk to the restaurants and bars on the main strip, close enough to get to easily but far enough away to escape the hullabaloo.
The room itself was a good size for the two of us (196 and 190cm) and there was plenty of room for our stuff - travelling rucksacks etc. The only downside was that the room was very hot and the ceiling fan didn't do a whole lot in cooling us down. It was fine for both of us as we can sleep relatively well in heat but might not be so good for people who struggle with that. Marion said she's getting an awning fitted to help with this in the next few days so this shouldn't be a problem much longer.
I'd definitely recommend and would absolutely stay there again if I return to Byron Bay.
