If you are looking South of town you have the following options along the beach:
Casa Gonzo, Casa Tortuga, The Palm House, View the Blue, Casa Rodundo and casa De Lisa and finally Villa Incommunicado
All these homes are on the beach ad provide easy access to town via walking, 5 minute air conditioned taxi, bicycle and of course golf cart. There is one other beachfront home that I do not know the name of because it is new but you can get the details from Mata Rocks Resort. For further details on any of these homes simply do a search on the internet.
