Stumbled upon this place at the beginning of the rainy season, so wasn't able to take full advantage of the amenities, but overall very happy. The location was perfect, can hear the waves from our room, granted it was during a tropical storm, but was still great. The staff was much warmer than in Jaco, even though only maybe 4 rooms occupied during this off season. The rooms were great; clean bed, bathroom, little kitchen with simple amenities. Was a bit pricey at $70, but after awhile realized that CR was not the bargain spot as thought, was fine. As noted, the location was excellent, at the end of the hotel past the mangrove on the beach is little restaurant/ bar. Casual and delicious. Even having breakfast during the storm, getting your food salted by the sea was doable.
Give the huge boxer Sampson a rub on his neck and you've got a friend for life!
After reading other reviews to compare, never saw the owners, didn't hear of any "breakfast included" and couldn't tell if gay friendly or not for lack of patrons, and only got to see the wildlife in the park.
Could tell you that if you go anywhere in CR during the "green season", be prepared for construction at all hotels!
The nice thing is the night staff throughout MA looks out for you and any "jungle bugs' hanging around.

What a great place to stay!
A friend recommended this place to me as he is a regular guest here. The place was very clean, room couldn’t have been more comfortable, and what a terrific team they have working there, and it felt more like a family then anything. Everyone there went out of their way to make sure my stay was super, and one desk clerk went way above and beyond his job in helping me out with a situation that came up in town while on my stay.
The beach is like a 5 minute walk, as well as the few good places to eat and hang out.
I would recommend this place to anyone.

Hotel del Mar is a small, quiet hotel within walking distance to Manuel Antonio National Park. Owners, David and Mark were extremely informative and so helpful with sharing information about the area. Luis, at the front desk always had a smile on his face and also was very candid about what to do and where to go. it is nice to know what the locals like and to get away from the biased tourist information that is in all the quidebooks and brochures. Someone is at the front desk 24/7. The breakfast was pastries from a local bakery and yummy fruit. There are tables and chairs outside the rooms as well as in a common area, where you can read, eat breakfast, or chat with other guests. It is located across the street from the beach and an easy walk to a few restaurants, the park and other hotels. The bus stop is very close by to ride to the other end of town. I recommend hiring a field guide at the Park, as he will be able to spot the sloths and explain more about the animals and plants along the way. Price is about $20 per person, in addition to the $10 fee for the park. Well worth the price, as there is almost no way to spot the several sloths without them being pointed out and you can take good photos through the guide's fieldscope with any type of camera. Awesome!

We stayed here during the end of our trip to Costa Rica. We chose one of the upgraded suites, which still only ran us about $80. All the employees here were helpful and friendly, though there it was sparsely staffed. It's very very close to the beach, and we had monkeys playing outside our window on occasion. A quick walk to the beach (~5 min), they let us conveniently leave our room key at the front desk every time we went out. They sell water and other refreshments right at the desk, which helped a lot after a long hike or a sunny day on the beach. They were great about calling cabs, and pitched in with some local reccomendations to eat and drink. We actually met one of the owners as well, who was very nice and appreciative of having us stay at his hotel. An important note: this is a gay friendly hotel. We are a hetero couple, and had no problems or uncomfortableness at all. That's not to say that every room was filled with gay couples, but this definitely isn't the place to stay if you have a problem with that.
