My fiance and I recently returned from a trip to Costa Rica. We were there to fish, surf and do the general eco-tourist thing, which is why we chose Quepos as our hub, as it has all three within a short distance.
On the recommendation of a friend, we stayed at the La Sirena Hotel. As we had planned to be gone fishing, surfing and hiking all day long, security was a major concern of ours. We were pleased to see how safe and secure the La Sirena was. It's a very clean and comfortable hotel with a quaint atmosphere and a nice tropical feel about it. It even has a swimming pool in the tropical center courtyard (The only hotel I noticed there with a pool) . The staff was very friendly and helpful, and spent a lot of time to assure that our stay was pleasant. They even serve breakfast!
The La Sirena is just minutes from everything. Surfing, fishing , nightlife, and Manuel Antonio which consists of some of the most beautiful beaches and hiking trails I've ever seen anywhere in the world. We walked most everywhere except Manuel Antonio which is just a few minutes by bus or car.
We will definitely return to Costa Rica and we will stay at the La Sirena and I highly recommend it for anybody looking for a nice affordable hotel in one of Costa Rica's nicest areas.
