Very nice and quiet location. End of a quiet street and surrounded by trees and bird sounds. Our 18 month old daughter was quite happy standing by the window and spotting birds and listening to their calls.
While the property is close to the beach on the map, it is not easy to access the beach, especially with a child. The restaurants etc. in Byron bay are close, 10-15 minute walk at most depending on the location. We didn't explore the building facilities much and when home stayed mostly in our unit.
The unit was nicely furnished. The kitchen was adequate for what we needed. The unit had a high chair which was great for our daughter. One small note about child friendliness. The unit has a stairs and furniture with sharp corners. So for people with small children, you have to always supervise them.
I would recommend the place to others. Great first time experience with both AirBnB and Byron Bay.
