My friends and I stayed at Cacti Mi Casa when up in Byron for Bluesfest - I have to say we lucked out with such a great place to stay - from the fantastic, open warehouse conversion space, excellent amenities including coffee machine, sonos speaker, foxtel, wifi to the thoughtful gifts on arrival and communication from Roxy, checking in throughout the visit to make sure all was ok, there was nothing negative at all about our stay.
The location itself was handy for the festival, some nice cafes and the Stone and Wood brewery within walking distance, but town and beaches only a 10 min ride on the bikes provided.
Would highly recommend and would certainly stay again when next in the area.
