The hotel was awesome! Very clean! Michael was excellent upon our arrival and check in. The only bummer is that there were many people at the outside restaurant that was loud until almost 1:00 am. Could sleep much but not sure it was the hotel’s issue.

Words cannot express the amazing experience we had at the terranea resort and spa . From beginning to end , we had a spectacular time !!!! We were celebrating our 20 wedding anniversary and their attention to detail was exquisite . Our concierge handled all our dinner reservations and we had such an extraordinary time. The views , our upgrade to the casita ! The service , the spa and all Our fabulous dinners were unlike no other . Staff was super happy and serviceable. Everyone was attentive and knowledgeable. Cenebio from the Mar’sel restaurant was amazing . It was one of the best dining experiences we have ever had . He was so great and made us feel so special He even took a picture of us having dinner overlooking the ocean and gave it to us in a beautiful card . It was one of the most memorable dining experiences of our 20 years of marriage together. Corey from Bashi was so sweet and attentive. He also made our celebration so special . Nelson’s was also great for lunch. All the chefs we had the pleasure of dining from were 5 stars . The details in everything were incredible The turn down service , the spa masseuses. AMAZING The spa itself is the main character in this picture . It truly felt like you were part of movie set . It was simply extraordinary . The views from everywhere were unbelievable. I cannot rave enough about how beautiful it all was . The hiking trials never disappoint. If you need some respite or some time off to disengage. This is the place!
