The Royal Corin Thermal Water Spa & Resort - Adults Only

Multiple guests praised very clean facilities and hot springs ("instalaciones impecables", "hot springs really nice and very clean"), but a serious maintenance/cleanliness failure was reported (AC/bath drainage leaks with brown water), so score is reduced slightly.

Overwhelmingly praised across reviews (staff very friendly, attentive, remembered names, exceptional reception service such as Deyber; many call staff the highlight). There are isolated service failures (negative attention from one staff member and a report of no assistance after a severe injury), but the dominant sentiment is excellent service, so this category is rated at the top to reflect consensus and to balance negative outliers.

Consistently noted for excellent location and stunning views of Arenal Volcano; some minor downsides mentioned (the ride to get there, and a concern about road proximity for one room), but overall location/view is a major positive.

Many comments about wonderful, spacious and comfortable rooms, but at least one severe maintenance issue (AC leaking and bathroom drainage problems) negatively affected a guest, so score is high but tempered.

Thermal pools, spa, pool areas and rooftop restaurant receive strong praise and are frequent highlights; however the gym was reported out of service during one stay, so a small deduction is applied.

Mixed signals: many guests praised food and service, but several called out high bar prices and an overpriced/poor restaurant experience; breakfast described as reasonable by some but underwhelming by others, resulting in a lower value perception.

Majority of reviews praise excellent food, rooftop restaurant and breakfast buffet (some call the chef and dining excellent), though a subset reported very poor restaurant quality and service and high prices; overall positive but with notable negative reports.

Most guests describe a wonderful, romantic or family-friendly stay they didn't want to leave, praising staff, pools and views. A single extremely negative, severe incident significantly detracts for that guest but does not outweigh the broadly positive consensus.
