I stayed at half-moon which is the small place at the front of a huge house also available for rent with the same owners. They park their car right beside your kitchen and use the driveway on the side.
So this place is comfortable and in a good location being close to the beach. The beach is great for dogs or even without a dog it's a lovely spot to walk along Belongil beach. Really nice people about. I went in winter. It is a fairly busy street even in winter but not much noticeable road noise.
I found the bed and linen very comfortable and the shower and bathroom very nice. The kitchen was good, practical and the crockery was ok but to be honest I went out to places for most meals. Coffee machine appreciated. You'll have to bring your own pods. The smart tv was great for a relaxing evening. The front yard was not big or very nice as it's mainly sand and dirt with a little grass. It is tiny and with a car also parked inside there is not a lot of room to sit or have your dog if you're bringing one. Although I enjoyed my stay a lot I feel this place was really over-priced compared to what I have experienced in life, maybe it is because it is Byron Bay and because it accepts dogs it has the monopoly over other nice units that will not take pet/s. I think it can be better set up for a pet with a dog bed provided and an improved outdoor area. I guess if I had paid less I wouldn't be as critical but that's why I am being specific here.
