My one night at the Atlantic was lovely. I was in Byron for a very short time and I wish I had been able to stay longer. The room was light and airy, clean and comfortable. Bathroom was modern and clean and I enjoyed being there. It's located very conveniently.
There is a communal aspect to the kitchen and garden with one washing machine. I could have done with doing a load of washing but it was in use - you win some... Byron is a very sociable place but I felt like I should have brought my own friends... I stayed here out of fear of all the "party" hostels there - made for a fairly sterile experience. The only fault is your "free wifi" extends to one email on your iphone - then I don't know what you do as the reception was closed at 6pm... thankfully there is an internet cafe at the end of the road with free wifi that you can catch on the street corner... just look for all the backpackers with laptops!
