While it's not located on the beach, the Gecko Resort is worth the short walk to get to Pattaya or Sunrise Beach. Centrally located right off of the island's main Walking Street, the Gecko offers South Pacific Island huts with the added benefit of hot water and reliable wifi. (It's important to note, that just because a place puts up a sign saying free wifi, does not mean that it's true.)
The couple that owns it is friendly and accommodating. And the resident cats will curl up with you on the porch should you be missing your own furry friend.
