My wife and I stayed at Sol y Viento for the first time in February 2014. We went because of the hot spring water. This is a large hotel with many pools of various sizes, temperatures. There is an extensive pool area for children on part of the property. We found the pools very clean and enjoyable.
We had two small complaint. First, we found the food and service at the restaurant rather poor. We were surprised at that because the restaurant is advertised as being a branch of the well-know Manila chain Barrio Fiesta, which is known for good, not-to-expensive Filipino food. This branch is below par, though. I suggest Barrio Fiesta management look into it. The breakfast food and service were a lot better than dinner.
The second problem was that our room was a 'loft', meaning the bed is upstairs from a tiny entryway and bathroom. We knew the room would be a loft, but we didn't anticipate how steep and slippery the stairs would be. It's not good for people who might have to use the bathroom during the night.
We will probably use Sol y Viento again but next time we'll rent a different type of room and bring our own food for dinner (there's a 'corkage' charge, though...).
