A friend and I recently stayed at the hacienda and had a great time. If you're looking for a place to relax, this will fit the bill. We did several excursions and the hacienda team was easy to work with when we set up the excursions (before arrival) and during our adventures. I was excited to try the local cuisine throughout our stay and the staff even went out to get a local soup for us to try one night.
I really enjoyed relaxing by the pool and in one of the hammocks with great views of the Masaya volcano over a few days. Definitely worth a trip if you're looking to relax.
