My family and I have been going to La Fonda for years. However, on our last trip, just about everything of value was stolen from the room. It is a great place, a somewhat shoddily maintained rooms (do not expect much in the rooms other than being perched above a cliff/beach)...it is the definition of quaint...but the location is good, the ambiance great, and the food--excellent. It's a great beach getaway...an hour across the border.
BUT...after going there for years, one day, our room was cleaned-out. Wallets, rings, etc. The owner, who we've known for years exclaimed that nobody, ever, had had anything stolen from his hotel. It found this totally implausable and definitely untrue. It is Mexico, surrounded by powerty, and theft in rooms is still commonplace.
Go, enjoy yourselves, but be sure to not let the serenity fool you. Watch your things. Take what you don't want to have stolen with you...or hide it well. Also, they do have a safe at reception. Keep important things there, maybe.
