We had three rooms on a family vacation, two sets of grandparents and two couples with kids 3,5 and 10 yrs old.
The rooms were adequate, although the bathroom was very cramped.
Dinners were excellent- thanks to Tony. We all wanted fish the second night, and Tony made an early morning trip for us to the local suppliers to cook up an excellent Pargo (snapper) dinner with a choice of excellent sauces. An upbeat chef that was in his element in the kitchen, the food was great.
The pool was very nice, much fun for the kiddos, and large enough to swim short laps in.
A huge beach great for sea shell hunting, and the rooms all look over the ocean for amazing sunsets. The ocean is not safe for swimming due to rip currents, but this is fairly common all along the Pacific Coast.
We were the only ones there, and the staff were not especially helpful or pleasant- had to ask to have pool lights turned on even though the bartender/helper (Miner) was right there. But I think they just are not service oriented and did not appear rude, just not used to looking out for the guests. Miner excelled at making fresh fruit based drinks.
The owner was there for one night and a morning- helped with the bags and greeted us on arrival, and had some good tips on getting through the tourist trap on Manuel Antonio National Park, which we felt to be overrated and was the low point of our three week trip in Costa Rica.

Loved the interior, the grand staircase and lofty ceiling had a nice atmosphere.

I recently stayed one night here with my Costa Rican girlfriend. We ordered two bowls of seafood soup. MISTAKE. It was what my girlfriend called sopa de agua, (water soup). We complained and only had to pay for one bowl of this so-called "soup". We were going to stay another night until we were told that their restaurant was closed and we were told to "find someplace else to eat". We checked out. Later, the Delfin Beachfront Resort tried to steal $75.00 from Bank of America on a blank voucher I had signed. Bank of America is well aware that I never pay for hotels with my VISA card and so relieved them of my money. Also there were fleas infesting the room. Never again....

I recently stayed at the Delfin and found a new group of friends there and a home away from home. The location is immaculate, the staff is friendly and accommodating, the pristine sandy beach is laced with beautiful seashells. My room overlooked the south facing beach, which allowed my wife and I to see the exotic sunrise and sunset. The Costa Rican style cuisine is wonderful. The hotel grounds are well kept and full of life. All in all I give the Delfin an A+.

I advise anybody reading this to NOT go to this hotel or restaurant. We went only for dinner and it was a joke. The owner sat at the bar the whole time with his friends - no welcome by him or anybody else for that matter. I have never been to an establishment where the owner was totally uninterested in his guests - as this guy was. not even a "thank you" or a "good bye". The bartender tried (somewhat) but was too busy making drinks for and chatting with the owner and girlfriend and friends that the service was very slow and unfriendly. They had no soap or towels for drying hands in the ladies bathroom. The beer was not cold and the bartender said that is just the way it is. I recommended putting it in a n ice bucket to get it colder and he said he was not allowed to do that. On the positive side, the fish was prepared well but served with mashed potatoes instead of rice - not a good pairing. Also, the bill was almost $45 dollars for two (this is the new Costa Rica). I was very disappointed.
