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.

We stayed at the Hotel Del Mar for nine days in February 2008. I've been to Manuel Antonio on five different occassions so I'm quite familiar with the area. We usually stay at very budget accommodations, which are very hard to find in this area. We decided to splurge this year and get a place that had air conditioning.

We were really pleased to walk into our room for the first time and see that it was so large. The area around the hotel is very quiet and this is not always the case along the hotel strip leading down to the park.

I'm a wildlife photographer by trade so I visit this region simply for the wildlife and I was so happy that we were on a major monkey route. We saw the endangered mono titi (red backed squirrel monkey) passing right by our hotel balcony at 5am and again at 1:30 p.m. each day. Capuchin Monkeys used the route at around 12:30 p.m. each day. It is common for monkeys to keep a "schedule" as they forage for food since various species don't like to run into each other. It's an easy bet that those monkeys will keep to a similar schedule for the forseeable futre. A two-toed (the more rare kind) sloth was hanging our on a tree right next to where breakfast was served.

Breakfast was very nice and there was a long period of time when it was served. The rooms were quite sheltered by trees so it was cool even without air conditioning.

We were helped a lot by Luis at the front desk. He was so friendly and helpful. His English is perfect and my husband was also able to practice spanish with him (Luis was very patient). Our stay was made so much better because of him. He went out of his way to help my husband who was sick and he was really fun to talk with at the end of the day. If you see Luis please tell him we say hi!

The cleaning staff kept the room mint clean and it was great that we could also order laundry service straight from our room, luxuries we aren't used to staying at hostels.

I should also mention that this hotel is very gay friendly, which was awesome. There was a schedule of gay-friendly activities at the front desk for their guests. The hotel is very inclusive.

I would highly recommend staying here!
