My girlfriend and I recently stayed at Alma Del Pacifica in January 2013. It was fantastic. Below is the breakdown.
Service: Overall I would give Alma a 4/5. Service was excellent from booking manuel antonio to activities at the hotel. My one small complaint would be food and beverage service. Having said that the waiters are great, kind and courteous but food/drinks always took a while. Personally, it didn't bother me but I could see how an older couple may get a little annoyed.
Rooms: We stayed in a garden villa and it was excellent. Extremely spacious, clean and beautiful. Room includes snacks, juice and a couple of bottles of waters that are replenished every day. For the price, it was and will be the nicest room I will ever stay at.
Beach: Empty, gorgeous, soft sand. One of the nicest beaches I have been too. I would go to Playa Esterillos over any clear water Caribbean beach. Simply breath taking.
Food: For breakfast the banana pancakes were impressive, my girlfriend loved them. For all other meals I stuck to seafood only because of the freshness. The snapper was delicious if you don't mind fried fish. I ordered the tuna both rare/medium rare and both were surpassed my standards for tuna. They also have great snacks for at the beach like chips and salsa. Do not expect a crazy gourmet meal but the meals were a great mix of freshness, american tastes with a slight costa rican flavor. I was never disappointed and would go to this restaurant if it was in NYC.
Drinks: The price was normal to slightly cheaper then expected. Blended drinks were a bit weak for my standards but my girlfriends seemed to love them.
Price: Simply unbeatable for the price. I'm sure no one has complained but if any reviewers did then "cheap" is not even a sufficient word to describe them.
Overall: I plan on coming back and I am not the type of person to revisit a destination. Overall excellence and made for excellent portion of our vacation. If you don't mind the inconveniences of its remote location then this hotel will keep you smiling your entire stay.
