We stayed here for 3 nights on our eco-tour with Collette Vacations. The grounds are beautiful with flowers everywhere. The location is spacious but that makes for a bit of walking, frequently uphill (but not steep). There is a beautiful pool, near the restaurant and heated by the local hot springs. It has a swim-up bar.
The whole resort has beautiful views of the volcano, although due to rain and mist, we only saw it briefly on two the early mornings.
The room was very nice. It was quite large but fairly plain. However, the bathroom was something else. It was very large (about 300 sq. ft.) with two showers, one of which was a waterfall. There was a skylight in the bathroom and it helped support the many ferns and other plants.
All of the rooms had a nice patio. Ours faced the volcano. The patios had hot tubs and rocking chairs. We never did try out the tub but the rocking chairs were well used.
Our one complaint was service. Only one room key was available, which was fine for us (a married couple who wanted to do the same things) but less than wonderful for those who had varied interests. Our tour guide left her key at the spa it was easily recovered) but the hotel staff would not give her a replacement. The safe in our room did not work (it was locked when we arrived). Eventually the staff sent someone to open it. However, when we tested it (thankfully empty), it would not reopen and no one ever fixed it.
Meals were good but service was slow (except at breakfast - a buffet).
The location is wonderful for lots of things to do. There is a beautiful spa that some of our group went to. Others of us went zip lining and/or horseback riding.
