We had a very restful stay at Sylvia's. The townhome is in a quiet residential community, a 10-minute walk to the beach through a national forest on a sandy path. The beach is totally deserted, great for a good long walk (but treacherous swimming signs when we were there). There are many other beaches a short drive away in addition. Note: you need a car here--not very walkable or bikeable unless you're daring. Byron Bay is a car culture.
The home is well appointed and spacious for four people (or more). Everything worked well, except for the wifi, which was very slow, even after rebooting. I was bumped when trying to do some wifi business calls. But otherwise the place is lovely. The favorite spot for all of us was the spacious deck in the morning, listening to the birds--it's like a jungle out there, in a good way. The saltwater pool in the complex is good for dipping in but too small for a good swim. Very nice stay overall.
