I went with a group of 11 to Orquidea del Sur for the last leg of a week-long trip to Nicaragua. Overall, the our stay was excellent. We were there for three nights over Thanksgiving and had an amazing time. We received excellent service and had the whole place to ourselves which, for a group of 11, was really nice. The spot is a cool mix of a bed and breakfast, luxury home, and hotel, with a huge, multi-level outside area for lounging, hammocking, relaxing at the bar, relaxing at the pool, and just relaxing. Did I mentioned it's relaxing?
The pristine beach in front of the Orquidea del Sure is an easy 10 min walk or quick drive if you have a car. The beach is gorgeous and during our stay we literally saw only a few other people on the beach at any given time. If you like to surf, especially if you're a beginner, this is a great place for you.
Overall, a place I definitely recommend and would go back to!
